128 16393983 However, OX40 costimulation, when combined with GM-CSF-secreting tumor-targeted vaccination, can break established CD8+ T cell tolerance in vivo by enhancing the expansion, and prolonging the survival and effector function of CD8+ T cells specific for RNEU420-429.
129 16393983 Moreover, we demonstrate that OX40 expression is up-regulated on both CD4+ and CD8+ T cells shortly after administration of a GM-CSF expressing vaccine.

178 18703465 Recently, it has been demonstrated that interaction between dendritic cells (DCs) and thymic stromal lymphopoietin (TSLP), an IL-7-like cytokine, is essential for evoking T(h)2 responses in allergy.
179 18703465 We demonstrated that BCG redirects TSLP-DCs away from inducing inflammatory T(h)2 cells that produce IL-4, IL-5, IL-13 and tumor necrosis factor (TNF)-alpha and toward regulatory T(h)1 cells that produce IFN-gamma and IL-10.
180 18703465 We also demonstrated that this functional alteration of TSLP-DCs by BCG depended on both production of IL-12 from DCs and down-regulation of OX40 ligand, a member of the TNF family, on DCs.
181 18941113 T-cell modulation was accomplished by targeting both effector and regulatory T-cell populations using systemic administration of monoclonal antibodies against OX40, CTLA4, GITR, and folate receptor 4 (FR4).

193 20121696 Two families of receptors, the CD28 family and the tumor necrosis factor receptor (TNFR) family, have been found to be major players in providing costimulation to CD8+ T cells.
194 20121696 Programmed death-1 (PD-1), another member of the CD28 family, may contribute to functional defects of helpless memory CD8+ T cells.
195 20121696 Members of the TNFR family, such as CD27, 4-1BB, CD40, TRAIL (tumor necrosis factor-related apoptosis-inducing ligand), and OX40, have also been implicated in the survival, generation, maintenance, and quality of virus-specific memory CD8+T cells.

201 20392496 IL-4 directs both CD4 and CD8 T cells to produce Th2 cytokines in vitro, but only CD4 T cells produce these cytokines in response to alum-precipitated protein in vivo.
202 20392496 While IL-4 directs CD4 T cells to produce Th2 cytokines (including IL-4, IL-13, IL-5) in vitro it has been shown that production of these cytokines can be induced in vivo in the absence of IL-4/IL-13/STAT-6 signaling.
203 20392496 The present report shows that CD8 as well as CD4 T cells activated through their TCR, in vitro upregulate the Th2-features - IL-4, IL-13, IL-5, and GATA-3.
204 20392496 However, in vivo while alum-precipitated antigen strongly and selectively induces these Th2-features in CD4 T cells, CD8 T cells mount a markedly different response to this antigen.
205 20392496 This CD8 response is associated with strong proliferation and production of IFN-gamma, but no Th2-features are induced.
206 20392496 Alum-protein formulations are widely used in human vaccines and typically induce strong antibody responses characterized by the differentiation of IL-4-producing CD4 T cells and immunoglobulin class switching to IgG1.
207 20392496 Analysis of the in vivo response to alum-precipitated protein shows that while subsets of CD4 T cells strongly upregulate Th2 and follicular helper T cell features including the surface markers OX40, CXCR5, PD-1, IL-17RB and the transcription factor c-Maf, CD8 T cells do not.
208 20392496 These discrete differences between responding CD4 and CD8 T cells provide further insight into the differences between Th2 polarization of CD4 T cells directed by IL-4 in vitro and the induction of IL-4 production by CD4 T cells in vivo in response to alum-precipitated protein.
209 21074068 OX40 and its ligand, OX40L, are key TNF members that augment T-cell expansion, cytokine production, and survival.
210 21154120 Targeted immunomodulatory therapy is focused primarily on the activation of costimulatory receptors (eg, 4-1BB, OX40 and GITR [glucocorticoid-induced TNF receptor-related gene]) or the blockade of co-inhibitory receptors (eg, CTLA-4, PD-1 and PD-L1) on T-cells during activation and/or effector responses.
211 21469117 Here, we show that IL-4 and IL-13 production is NF-κB1-dependent in mouse OVA-specific CD4(+) (OTII) T cells responding to alum-precipitated OVA (alumOVA) immunization.
212 21469117 More surprisingly, we found that NF-κB1 deficiency in OTII cells also selectively impairs their CXCR5 induction by alumOVA without affecting upregulation of BCL6, IL-21, OX40 and CXCR4 mRNA and PD-1 protein.
213 21469117 The selective effects of NF-κB1-deficiency on Th2 and follicular helper T cell induction do not appear to be due to altered expression of the Th2-associated transcription factors - GATA-3, c-Maf and Ikaros.
214 21469117 Altogether, these results suggest that NF-κB1 regulates the expression of CXCR5 on CD4(+) T cells primed in vivo, and thus selectively controls the T-cell-dependent germinal center component of B-cell response to alumOVA.
215 21715499 Targeting OX40 promotes lung-resident memory CD8 T cell populations that protect against respiratory poxvirus infection.

249 22266281 OX40 ligand and programmed cell death 1 ligand 2 expression on inflammatory dendritic cells regulates CD4 T cell cytokine production in the lung during viral disease.
250 22266281 Using a mouse model in which vaccination with vaccinia virus vectors expressing the respiratory syncytial virus (RSV) fusion protein (rVVF) or attachment protein (rVVG) leads to type 1- or type 2-biased cytokine responses, respectively, upon RSV challenge, we found expression of CD40 and OX40 ligand (OX40L) on lung inflammatory DCs was higher in rVVF-primed mice than in rVVG-primed mice early after RSV challenge, whereas the reverse was observed later in the response.
251 22266281 In contrast, PD-L2 promoted IFN-γ production, irrespective of conditions, suppressing IL-5 only if expressed on type 1-biased DCs.
252 22956587 T cell costimulation by TNFR superfamily (TNFRSF)4 and TNFRSF25 in the context of vaccination.
253 22956587 TNFR superfamily (TNFRSF)4 (OX40, CD134) and TNFRSF25 are costimulatory receptors that influence CD4(+) and CD8(+) T cell responses to cognate Ag.
254 22956587 Independently, these receptors have been described to stimulate overlapping functions, including enhanced proliferation and activation for both regulatory T cells (CD4(+)Foxp3(+); Tregs) and conventional T cells (CD4(+)Foxp3(-) or CD8(+)Foxp3(-); Tconvs).
255 22956587 To determine the relative functionality of TNFRSF4 and TNFRSF25 in T cell immunity, the activity of TNFRSF4 and TNFRS25 agonistic Abs was compared in the context of both traditional protein/adjuvant (OVA/aluminum hydroxide) and CD8(+)-specific heat shock protein-based (gp96-Ig) vaccine approaches.
256 22956587 These studies demonstrate that both TNFRSF4 and TNFRSF25 independently and additively costimulate vaccine-induced CD8(+) T cell proliferation following both primary and secondary Ag challenge.
257 22956587 In contrast, the activities of TNFRSF4 and TNFRSF25 were observed to be divergent in the costimulation of CD4(+) T cell immunity.
258 22956587 TNFRSF4 agonists were potent costimulators of OVA/aluminum hydroxide-induced CD4(+) Tconv proliferation, but they only weakly costimulated Treg proliferation and IgG2a production, whereas TNFRSF25 agonists were strong costimulators of Treg proliferation, producers of IgG1, IgG2a, and IgG2b, and weak costimulators of CD4(+) Tconv proliferation.
259 22956587 Interestingly, Ag-specific cellular and humoral responses were uncoupled upon secondary immunization, which was dramatically affected by the presence of TNFRSF4 or TNFRSF25 costimulation.
260 22956587 These studies highlight the overlapping but nonredundant activities of TNFRSF4 and TNFRSF25 in T cell immunity, which may guide the application of receptor agonistic agents as vaccine adjuvants for infectious disease and tumor immunity.
261 22956587 T cell costimulation by TNFR superfamily (TNFRSF)4 and TNFRSF25 in the context of vaccination.

264 22956587 To determine the relative functionality of TNFRSF4 and TNFRSF25 in T cell immunity, the activity of TNFRSF4 and TNFRS25 agonistic Abs was compared in the context of both traditional protein/adjuvant (OVA/aluminum hydroxide) and CD8(+)-specific heat shock protein-based (gp96-Ig) vaccine approaches.
265 22956587 These studies demonstrate that both TNFRSF4 and TNFRSF25 independently and additively costimulate vaccine-induced CD8(+) T cell proliferation following both primary and secondary Ag challenge.
266 22956587 In contrast, the activities of TNFRSF4 and TNFRSF25 were observed to be divergent in the costimulation of CD4(+) T cell immunity.
267 22956587 TNFRSF4 agonists were potent costimulators of OVA/aluminum hydroxide-induced CD4(+) Tconv proliferation, but they only weakly costimulated Treg proliferation and IgG2a production, whereas TNFRSF25 agonists were strong costimulators of Treg proliferation, producers of IgG1, IgG2a, and IgG2b, and weak costimulators of CD4(+) Tconv proliferation.
268 22956587 Interestingly, Ag-specific cellular and humoral responses were uncoupled upon secondary immunization, which was dramatically affected by the presence of TNFRSF4 or TNFRSF25 costimulation.
269 22956587 These studies highlight the overlapping but nonredundant activities of TNFRSF4 and TNFRSF25 in T cell immunity, which may guide the application of receptor agonistic agents as vaccine adjuvants for infectious disease and tumor immunity.

315 23372784 Following long-term infection with virus derived from the pathogenic GL8 molecular clone of feline immunodeficiency virus (FIV), a range of viral variants emerged with distinct modes of interaction with the viral receptors CD134 and CXCR4, and sensitivities to neutralizing antibodies.
316 23372784 Infection with either clonal (Group 1) or diverse (Group 2) challenge viruses, resulted in a reduction in CD4+ lymphocytes and an increase in CD8+ lymphocytes.
317 23372784 Marked differences in the ability of individual viral variants to replicate were noted in Group 2; those most similar to GL8 achieved higher viral loads while variants such as the chimaeras bearing the B14 and B28 Envs grew less well.
318 23372784 However, in vitro studies indicated that the reduced replicative capacity of variants B14 and B28 in vivo was associated with altered interactions between the viruses and the viral receptor and co-receptor.
319 23460531 The list of antagonist agents acting on repressors under development includes anti-CTLA-4, anti-PD-1, anti-PD-L1 (B7-H1), anti-KIR, and anti-TGF-β.
320 23460531 Agonist antibodies currently being investigated in clinical trials target CD40, CD137 (4-1BB), CD134 (OX40), and glucocorticoid-induced TNF receptor (GITR).
321 23897980 Together, these findings suggest that human OX40 is necessary for robust CD4(+) T cell memory and confers apparently selective protective immunity against HHV-8 infection in endothelial cells.
322 23947352 The contextual role of TNFR family members in CD8(+) T-cell control of viral infections.
323 23947352 The role of specific TNF receptor (TNFR) family members in antiviral immunity depends on the stage of the immune response and can vary with the virus type and its virulence.
324 23947352 Here, we focus on five members of the TNFR family that are prominently expressed on CD8(+) T cells during viral infections, namely, 4-1BB (CD137), CD27, OX40 (CD134), GITR, and TNFR2. 4-1BB, CD27, OX40, and GITR have primarily prosurvival roles for CD8(+) T cells during viral infection, although under some circumstances 4-1BB, GITR, or CD27 signals can limit immunity.
325 23947352 Although TNFR2 can be costimulatory under some circumstances, its main role in CD8(+) T-cell responses during viral infection appears to be in contraction of the response.
326 23947352 Several TNF family ligands are being explored as adjuvants for viral vaccines, and agonistic antibodies to TNFR family members are being investigated for immunotherapy of chronic viral infection alone and in combination with checkpoint blockade.
327 24014877 Therefore, much effort has been made to generate agonistic Abs targeting members of the TNFR superfamily, such as OX40, 4-1BB, and GITR, expressed on effector T cells and Tregs, to reinvigorate T cell effector function and block Treg-suppressive function.
328 24014877 In this article, we describe the development of a panel of anti-human OX40 agonistic mouse mAbs that could promote effector CD4(+) and CD8(+) T cell proliferation, inhibit the induction of CD4(+) IL-10 -producing type 1 regulatory T cells, inhibit the expansion of ICOS(+)IL-10(+) Tregs, inhibit TGF-β-induced FOXP3 expression on naive CD4(+) T cells, and block natural Treg-suppressive function.

331 24177180 Mechanistically, this treatment increased T and B cell responses to reporter antigen immunizations, led to preferential upregulation of OX40 on CD4(+) FoxP3(+) regulatory T cells in tumor-infiltrating lymphocytes, and increased the antitumor reactivity of T and B cells in patients with melanoma.
332 24732076 In mouse tumor models, engagement of activating Fcγ receptor (FcγR)-expressing immune cells was recently shown to be required for the tumoricidal activity of antibodies recognizing the tumor necrosis factor superfamily receptor (TNFR) GITR (CD357) and CTLA-4 (CD152).
333 24732076 Here, we explored the mechanism of antitumor activity mediated by an agonistic antibody (clone OX86) to the co-stimulatory TNFR OX40 (CD134).
334 25128713 The frequency of CD4+ cells among TCRαβ+ lymphocytes, as well as that of reactivated CD134(OX40)+ cells within its CD4+ T-lymphocyte subpopulation, was less in spinal cords of aged compared with young rats.
335 25128713 Additionally, CD134 surface density on CD4+ lymphocytes was decreased in the spinal cord of aged rats.
336 25128713 The changes in CD134 expression most likely reflected in part age-related intrinsic changes in CD4+ lymphocytes as the expression of this molecule was also impaired on in vitro stimulated naïve CD4+ splenocytes from aged rats compared with young animals.
337 25128713 In addition, greater frequency of CD8+ lymphocytes with regulatory phenotypes could also contribute to impaired CD4+ cell reactivation in aged rats.
338 25128713 The increased apoptosis of CD4+ cells from aged rats was consistent with their impaired reactivation and it was accompanied by the greater frequency of CD4+CD11b+CD45(int/high) cells, which are supposed to be actively engaged in apoptotic cell phagocytosis and to have immunoregulatory properties.
339 25128713 Compared with young rats, following short-term PMA and ionomycin stimulation in vitro, the frequency of IL-17+ and IFN-γ+CD4+ T lymphocytes among the spinal cord mononuclear cells from aged rats and the cytokine expression density on a per lymphocyte basis were reduced.
340 25128713 Additionally, the increase in the proportion of autoregulatory IL-17+IL-10+ cells on the account of proinflammatory IL-17+IFN-γ+ cells within IL-17+ lymphocytes suggested their lower pathogenic capacity in aged rats.
341 25128713 This most likely reflected alterations in the aged rat spinal cord cytokine milieu, which were mirrored in a diminished expression of IL-1β mRNA followed by an enhanced expression of IL-6 and TGF-β mRNA.

358 25595261 The rat susceptibility to EAE induction, as well as the number of activated CD4+CD134+ lymphocytes retrieved from their spinal cords progressively decreased with aging.
359 25595261 To the contrary, in rats immunized for EAE the number of activated CD4+ splenocytes, i.e., CD4+CD134+, CD4+CD25+FoxP3- and CD4+CD40L+ cells, progressively increased with aging.
360 25595261 This was associated with age-related increase in (i) CD4+ splenocyte surface expression of CD44, the molecule suggested to be involved in limiting emigration of encephalitogenic CD4+ cells from spleen into blood and (ii) frequency of regulatory T cells, including CD4+CD25+FoxP3+ cells, which are also shown to control encephalitogenic cell migration from spleen into the central nervous system.
361 25595261 In favor of expansion of T-regulatory cell pool in aged rats was the greater concentration of IL-10 in unstimulated, Concanavalin A (ConA)- and myelin basic protein (MBP)-stimulated splenocyte cultures from aged rats compared with the corresponding cultures from young ones.
362 25595261 Consistent with the age-related increase in the expression of CD44, which is shown to favor Th1 effector cell survival by interfering with CD95-mediated signaling, the frequency of apoptotic cells among CD4+ splenocytes, despite the greater frequency of CD95+ cells, was diminished in splenocyte cultures from aged compared with young rats.
363 25595261 In addition, in control, as well as in ConA- and MBP-stimulated splenocyte cultures from aged rats, despite of impaired CD4+ cell proliferation, IFN-γ concentrations were greater than in corresponding cultures from young rats.
364 25595261 The diminished CD4+ cell proliferation in response to ConA and MBP in splenocyte cultures from aged compared with young rats could be, at least partly, associated with an enhanced splenic expression of iNOS mRNA in aged rats.
365 25595261 The rat susceptibility to EAE induction, as well as the number of activated CD4+CD134+ lymphocytes retrieved from their spinal cords progressively decreased with aging.
366 25595261 To the contrary, in rats immunized for EAE the number of activated CD4+ splenocytes, i.e., CD4+CD134+, CD4+CD25+FoxP3- and CD4+CD40L+ cells, progressively increased with aging.

372 25816350 Co-expression of CD25, CD134, CD39 and FoxP3 was used to delineate both antigen-specific Tregs and effectors T cells (Teffs).
373 25816350 Vaccinees who displayed lower levels of HIV-specific CD4+CD134+CD25+CD39+FoxP3+ Tregs responded better to the LIPO-5-DC vaccine.

376 25944279 Consistently, at the peak of the disease greater number of reactivated CD4+CD134+CD45RC- T lymphocytes was retrieved from male rat spinal cord.
377 25944279 Additionally, oppositely to the expression of mRNAs for IL-12/p35, IL-10 and IL-27/p28, the expression of mRNA for IL-23/p19 was upregulated in male rat spinal cord mononuclear cells.
378 25944279 Within this subpopulation, the IL-17+IFN-γ+:IL-17+IL-10+ cell ratio was shifted towards IL-17+IFN-γ+ cells, which have prominent tissue damaging capacity.
379 25944279 This was associated with an upregulated expression of mRNAs for IL-1β and IL-6, but downregulated TGF-β mRNA expression in male rat spinal cord mononuclear cells.
380 25944279 The enhanced GM-CSF mRNA expression in these cells supported the greater pathogenicity of IL-17+ T lymphocytes infiltrating male spinal cord.
381 25944279 In the inductive phase of the disease, contrary to the draining lymph node, in the spinal cord the frequency of CD134+ cells among CD4+ T lymphocytes and the frequency of IL-17+ cells among T lymphocytes were greater in male than in female rats.
