To examine the feasibility of cytokine gene transfer into human renal cancer (RC) cells, we introduced the cDNAs for human interleukin-2 (IL-2) or interferon-gamma (IFN-gamma) into various RC cell lines with retroviral vectors.
|
2 |
1423266
|
Depending on the cell line and the vector construct used, lymphokine gene-modified human RC cell lines released 4 to 29 units/10(6) cells of IL-2, or up to 10 units/10(6) cells of IFN-gamma within 48 h.
|

1423266
|
Fluorescence-activated cell sorter analysis of SK-RC-29 cells releasing IFN-gamma showed increased expression of major histocompatibility complex class I antigen, beta 2-microglobulin, and ICAM-1, as well as induction of major histocompatibility complex class II antigen expression [human leukocyte antigen(HLA)-DR, -DP], but no changes in these cell surface markers were observed with SK-RC-29 cells releasing IL-2.
|
4 |
1423266
|
Tumor formation by the human RC cell line SK-RC-29 in BALB/c nude mice was not affected by IFN-gamma secretion, but was inhibited by in vivo release of IL-2 from s.c. injected tumor cells.

Mice with a targeted disruption in the beta 2-microglobulin (beta 2m) gene, which lack major histocompatibility complex class I molecules and consequently fail to develop functional CD8 T cells, provided a useful model for assessing the role of class I-restricted T cells in resistance to infection with virulent Mycobacterium tuberculosis.

Cellular proteins associated with immunodeficiency viruses were identified by determination of the amino acid sequence of the proteins and peptides present in sucrose density gradient-purified human immunodeficiency virus (HIV)-1, HIV-2, and simian immunodeficiency virus (SIV). beta 2 microglobulin (beta 2m) and the alpha and beta chains of human lymphocyte antigen (HLA) DR were present in virus preparations at one-fifth the concentration of Gag on a molar basis.

MxA gene expression is known to be regulated tightly and exclusively by type I interferons (IFNs).
|
18 |
7510764
|
A reliable induction of MxA RNA and MxA protein was found in the absence of easily detectable serum IFN activity.
|
19 |
7510764
|
The IFN marker 2'-5'-oligoadenylate (2-5A) synthetase known to react to both type I and type II IFNs showed a similar response but did not differentiate equally well between nonimmune and immune vaccinees. beta 2-microglobulin and neopterin reacted poorly, remaining at low levels within the normal range.
|
20 |
7510764
|
These results demonstrate that MxA gene expression is a good marker for detecting minute quantities of biologically active type I IFN during viral infections.

To identify the potential antigens involved in this protection, macaques were immunized with uninfected human cells, sucrose density gradient-purified culture fluid from uninfected human cells (mock virus), beta-2 microglobulin (beta 2M), immunoaffinity-purified HLA class I and class II proteins from these human cells, and adjuvant.

Mutant mice with a defined genetic defect in the beta 2-microglobulin (beta 2m) or the H2-I-A beta chain, which are virtually devoid of functional CD8 or CD4 alpha beta T cells, respectively, were employed for analyzing immune mechanisms involved in acquired resistance against Listeria monocytogenes.
|
23 |
7726898
|
These data demonstrate the importance of both MHC I- and MHC II-dependent immune mechanisms in acquired resistance to L. monocytogenes and point to the necessity of a coordinated interaction between CD8 and CD4 alpha beta T cells (and probably gamma delta T cells) in anti-L. monocytogenes resistance.
|
24 |

|
Mice with a homologous deletion of the beta 2-microglobulin gene (beta 2m-) are deficient in class I major histocompatibility complex molecules (MHC) and consequently are deficient in CD8+ T cells.
|
25 |
7768622
|
These data document the kinetics of gamma delta T cells reactive to mycobacterial antigens in vivo without class I MHC restriction and support a role for class I MHC and CD8+ T cells in the in vivo regulation of gamma delta T cells.

With this procedure, beta 2-microglobulin, HLA-DR, intercellular adhesion molecule-1, and leukocyte function antigen-1 were found on HIV-1 particles from laboratory strains and primary clinical isolates.

27 |

|
In contrast, CD19, CD4, and CD8 molecules were not detected.
|
28 |

|
Mice transgenic for beta 2-microglobulin deletion (beta 2M-/-) were immunized intranasally with either a recombinant vaccinia virus that expressed both nucleoprotein and interleukin-2 or by infection with H3N2 influenza virus; 3-4 weeks later they were challenged with H1N1 influenza virus.

MHC class I-dependent presentation of exoerythrocytic antigens to CD8+ T lymphocytes is required for protective immunity against Plasmodium berghei.
|

8617963
|
In this study, we wished to define the role of CD8+ T cells and MHC class I molecules by using the P. berghei malaria attenuated sporozoites (SPZ) protection model in beta 2-microglobulin (beta 2m) knockout (-/-) mice.

Expression of HLA class I molecules and the transporter associated with antigen processing in hepatocellular carcinoma.
|
32 |
8621152
|
Although HLA-A antigens were detected by CMC in all cell lines tested, HLA-B and -C antigens were not detectable in six of seven HCC cell lines.
|
33 |
8621152
|
Furthermore, complementary DNA (cDNA) from each cell line was tested for the expression of HLA-A, -B, -C and the transporter associated with antigen processing genes (TAP1 and TAP2).
|
34 |
8621152
|
The selective loss of HLA-B and -C, but not -A, molecules (which also excludes a beta 2-microglobulin defect) is intriguing, and may be attributable to the ability of some of the HLA-A molecules to load signal peptides not requiring TAP transport, or to natural selection of HLA-B or -C locus-specific immune surveillance.

Recombinant derived H-2Kb and beta 2-microglobulin (beta 2m) were properly folded into an MHC class I complex using the vesicular stomatitis virus (VSV)-8mer from the natural nucleocapsid proteinN52-59 (RGYVYQGL), an immunodominant Kb epitope in C57BL/6 (B6) mice.

Vaccination of immunocompetent mice elicits a CD8+ CTL response that can protect the mice from lethal meningitis. beta 2 microglobulin-deficient (beta 2m-/-) mice are deficient in CD8+ CTL, exhibit CD4+ CTL, and, after i.c.

Plasma levels of HIV-1 RNA, p24 antigen, antibodies to HIV-1 structural genes, beta-2 microglobulin, neopterin, and interferon-alpha were measured at four time points: (a) the last seronegative visit, (b) the first seropositive visit, (c) the visit closest to AIDS (or the corresponding visit for the non-RPs) and (d) 6 years after seroconversion (for non-RPs).
|
39 |
8970472
|
At the first seropositive visit, RPs had significantly higher concentrations of plasma HIV-1 RNA (p < 0.01) and prevalence of p24 antigenemia (p < 0.001) and significantly lower levels of antibodies to the HIV-1 gag proteins p17 and p24 (p < 0.01-0.001) compared with non-RPs.
|
40 |
8970472
|
Antibodies to p66 and gp120 were significantly different only at the visit closet to AIDS (p < 0.001), as were beta-2 microglobulin and interferon alpha.

CD8+ T cells are essential for protection against mycobacteria, as is clearly demonstrated by the fatal outcome of experimental infection of beta-2 microglobulin knockout mice.
|
45 |
9009330
|
This response is mediated by CD8+ T cells and absolutely requires the activation of CD4+ T cells and their secretion of interleukin 2.
|
46 |

|
Our results indicate that MHC-linked genes exert a profound influence on the generation of CD8+ CTLs following BCG vaccination.
|
47 |
9101413
|
Moreover, depletion of CD8+ T cells before transfer resulted in the loss of antitumor activity, despite the presence of CD4+ T cells.
|
48 |
9101413
|
In contrast, antitumor activity was demonstrable with CD8-containing, CD4-depleted effectors, although it was not as effective as with both T-cell subpopulations combined.
|
49 |
9101413
|
Finally, in beta 2-microglobulin/CD8+ T-cell-deficient mice, rV-CEA immunization exerted only partial antitumor protection, compared with the immune-competent controls.
|
50 |
9101413
|
Overall, we demonstrated that (a) antitumor activity induced by rV-CEA was essentially mediated by CD8+ effectors; and (b) the combination of both CD8+ and CD4+ lymphocytes led to maximal antitumor therapeutic effects, suggesting an important helper or immunoregulatory contribution of the CD4+ subset.

The animal model used was Human Human D(b) (HHD) mice, which are deficient for mouse MHC class I molecules (beta(2)-microglobulin(-/-) D(b-/-)) and transgenic for a chimeric HLA-A*0201/D(b) molecule covalently bound to the human beta(2)-microglobulin (HHD(+/+)).
|
58 |
11035120
|
Moreover, genetic immunization of HLA-A2 transgenic mice generates IFN-gamma-secreting CD8(+) T lymphocytes specific for endogenously processed peptides and with recognition specificities similar to those described during self-limited infection in humans.

|
CD4+ alpha beta T cells and gamma interferon (IFN-gamma) are centrally implicated in the primary immunoprotective response.
|
60 |
11035735
|
We find that a full-strength primary response depends on beta(2)-microglobulin (class I major histocompatibility complex [MHC] and class II MHC and on IFN-gamma and interleukin-6 (IL-6) but not on TAP1, perforin, IL-4, Fas ligand, or inducible nitric oxide synthetase.
|
61 |
11035735
|
Indeed, MHC class II-deficient and IFN-gamma-deficient mice are as susceptible to primary infection as mice deficient in all alpha beta T cells.
|
62 |
11035735
|
Strikingly, the requirements for a highly effective alpha beta-T-cell-driven memory response are less stringent, requiring neither IFN-gamma nor IL-6 nor class I MHC.
|

This was not restored by adding exogenous beta(2)-microglobulin to stabilize the MHC complex on the cell surface.

Induction of cross clade reactive specific antibodies in mice by conjugates of HGP-30 (peptide analog of HIV-1(SF2) p17) and peptide segments of human beta-2-microglobulin or MHC II beta chain.
|
65 |
11535326
|
HGP-30, a 30 amino acid synthetic peptide homologous to a conserved region of HIV-1(SF2) p17 (aa86-115), has previously been shown to elicit both cellular and humoral immune responses when conjugated to KLH and adsorbed to alum.

The purified MHC alpha chain is refolded with beta-2-microglobulin and the target peptide antigen to form the class I MHC.

|
Here we show that targeting of antigen to Fc receptors on DCs accomplishes combined activation of Th1 CD4 and CD8 effector responses in vivo, namely delayed-type hypersensitivity and tumor immunity.
|
69 |
12093890
|
Tumor protection was eliminated when immune complex-loaded DCs lacked beta(2) microglobulin, TAP, or MHC class II, demonstrating that Fc receptor-targeted antigenic uptake led to both MHC class I- and class II-restricted responses, which together are required for effector tumor immunity.

|
By contrast, Ig mu-chain gene KO mice, as well as Fcgamma receptor I/III, beta-2 microglobulin, CD1, monocyte chemoattractant protein 1 (MCP1), IFN-gamma, and perforin gene KO mice were protected.
|
71 |
12697735

Few mice were cured that had knockouts of the gene for Ig mu-chain, Fcgamma receptor I/III, IFN-gamma, or beta-2 microglobulin.

|
T-cell subset depletion experiments clearly indicate that elicitation of CD8(+) (as well as CD4(+)) effector responses is required for protection.
|
75 |
12761096
|
Further, mice lacking beta(2)-microglobulin (and hence deficient in major histocompatibility complex class I antigen presentation) were not able to control a challenge infection after vaccination, indicating an essential protective role for CD8(+) T effector responses.
|
76 |
12761096
|
Early postinfection in protectively vaccinated mice, a predominance of CD8(+) T cells, secreting gamma interferon (IFN-gamma) and expressing perforin, was observed at the site of infection; subsequently, activated CD4(+) T cells producing IFN-gamma were primarily found.
|
77 |
12761096
|
As protection correlated with the ratio of total IFN-gamma-producing cells (CD4(+) and CD8(+) T cells) to macrophages found at the site of infection, a role for IFN-gamma was evident; in addition, vaccination of IFN-gamma-deficient mice failed to provide protection.
|
78 |
12761096
|
Thus, the elicitation of CD8(+) T cell effector mechanisms (perforin, IFN-gamma) are clearly required in the protective immune response against L. amazonensis infection in vaccinated mice.

The L.E.A.P.S. heteroconjugate vaccine antigen (JgD), composed of a T cell epitope from glycoprotein D (gD(8-23)) of herpes simplex virus (HSV) linked with a peptide sequence from beta-2-microglobulin (aa38-50), elicited protection against lethal intraperitoneal (IP) challenge and prevented disease signs in most, and limited disease progression, for the rest of BALB/c mice challenged in the epidermal abrasion-zosteriform spread mouse infection model.

|
This technology utilizes specific peptides which bind to CD4, CD8 or other proteins on the surface of T cells (T cell binding ligand (TCBL)), macrophage and dendritic cells (immune cell binding ligand (ICBL)) to promote the immunogenicity of an epitope, activate T cell and other protective responses, and direct the immune response to either a Th1 or a Th2 type of response.
|
81 |
15569635
|
The J TCBL/ICBL is a peptide from beta-2-microglobulin which binds to the CD8 protein and promotes Th1 responses and the G TCBL/ICBL is a peptide from the beta chain of MHC II molecules that binds to the CD4 protein and promotes Th2 responses.
|
82 |
15569635
|
The JH1, JH2, JgB and JgD vaccines elicited DTH responses without antibody but conferred protection upon lethal challenge.
|
83 |
15569635
|
Initiation of the immune response by the JgD vaccine was dependent on functional CD4, CD8 expressing cells and interferon gamma and delivery of protection was dependent upon CD4 and interferon gamma.

|
Using beta(2)-microglobulin-knockout, IFN-gamma-knockout, and B cell-deficient mice, CD4(+) and CD8(+) cell depletion, and Ab transfer studies, we show that induction of anti-HER-2/neu Abs are both necessary and sufficient for protection, and the IgG2a isotype is most effective.
|
87 |
15778385
|
In contrast, CD8(+) T cells are not necessary at all, and CD4(+) T cells are necessary for only 36-48 h after immunization to provide help for B cells but not as effector cells.

Recently we reported that Cpn-infected mice generate an MHC class I-restricted CD8(+) Tc1 response against various Cpn Ags, and that CD8(+) CTL to multiple epitopes inhibit Cpn growth in vitro.
|
89 |
15843575
|
CD8(+) T cell lines generated to minigene-encoded CTL epitopes secreted IFN-gamma and TNF-alpha and exhibited CTL activity upon recognition of Cpn-infected macrophages.
|
90 |
15843575
|
Immunization and challenge studies with beta(2)-microglobulin(-/-) mice indicated that the reduction of lung Cpn burdens was mediated by the MHC class I-dependent CD8(+) T cells to minigene-included Cpn CTL epitopes, rather than by pan-DR epitope-specific CD4(+) T cells.

Here, we report time-course changes in expression levels, assessed by real-time RT-PCR of IL-1 beta, Mx, two beta-2-microglobulin variants and MHC class II beta, from 2 to 19 days post vaccination with a multi-component oil-adjuvanted vaccine.

We thus investigated the expression pattern of six chicken genes, including beta-actin, 28S rRNA, 18S rRNA, glyceraldehyde-3-phosphate dehydrogenase (GAPDH), TATA box-binding protein (TBP) and beta-2-microglobulin, in chicken embryo (CE) cell cultures following a 7-day IBDV infection.
|
93 |
16159698
|
The results showed that beta-actin, 28S rRNA, 18S rRNA and GAPDH were the most constantly expressed genes, while TBP and beta-2-microglobulin were markedly induced during the infection course.
|
94 |
16159698
|
Of these constant expressed genes, 28S rRNA and 18S rRNA are highly expressed; beta-actin intermediately expressed and GAPDH had a lower expression level in CE cell cultures.

Both CD4+ and CD8+ T cells can mediate vaccine-induced protection against Coccidioides immitis infection in mice.
|
99 |
16586371
|
Vaccine-induced immunity required alpha beta T lymphocytes. beta -2 microglobulin knockout (KO) mice were protected by immunization, and we transferred protection using CD4+ T cells from immunized mice.
|
100 |
16586371
|
However, vaccination also protected CD4+ KO mice, which suggests that CD8+ T cells played a role in vaccine-induced immunity, even though they were not required.
|
101 |
16586371
|
We adaptively transferred protection using spleen cells from immunized CD4+ KO mice to nonimmune B6 mice, but CD8+ -depleted spleen cells did not protect against infection.
|
102 |
16586371
|
Recipients of spleen cells from immunized CD4+ KO mice had 6 times more tumor necrosis factor (TNF)- alpha mRNA in their lungs than did mice that received nonimmune spleen cells, and TNF receptor-1 KO mice were not fully protected by immunization.
|
103 |
16586371
|
These results show that both CD4+ and CD8+ T cells can protect against coccidioidomycosis and that TNF- alpha is a necessary component of the acquired immune response.

To investigate correlates of these HIV-1-specific responses, we examined levels of the immune activation markers neopterin, beta(2)-microglobulin (beta(2)-m), and soluble l-selectin (sl-selectin); the immunomodulatory and hematopoietic factors interleukin-7 (IL-7), stromal-cell-derived factor 1 alpha (CXCL12), and granulocyte-macrophage colony-stimulating factor (GM-CSF); and the immunoregulatory cytokine IL-10 among a group of newborns born to HIV-1-positive mothers who did not receive any antiretroviral drugs for prevention of perinatal HIV-1 transmission.

We demonstrate that the beta(2)-microglobulin-linked epitope induced an accelerated and augmented CD8(+) T-cell response.

Notably, in contrast to full-length protein, the response elicited with the beta(2)-microglobulin-linked LCMV-derived epitope was CD4(+) T-cell independent.

Furthermore, virus-specific CD8(+) T cells primed in the absence of CD4(+) T-cell help were sustained in the long term and able to expand and control a secondary challenge with LCMV.
