The results show that a variety of differentiation molecules, proteins involved in the control of apoptosis, the B-cell transcription factors, positive regulatory domain I-binding factor 1/B lymphocyte-induced maturation protein 1 and B cell-specific activating protein and, at least partially, the chemokine receptor CXCR4 were expressed by human PCs following a gradient of increasing maturity in the direction: tonsil-->blood-->BM.

We show that immature and transitional 1 (immature/T1) B cells constitutively express activation-induced cytidine deaminase and B lymphocyte-induced maturation protein 1 in amounts that support accelerated plasmacytic differentiation and limited class-switch recombination.

In response to TLR7/8 stimulation, PDCs mediated the up-regulation of transcription factors B lymphocyte-induced maturation protein 1 and X-box binding protein 1 and enhanced differentiation of B cells into IgM-, IgG-, and IgA-producing cells.
|

19201852
|
Although MDCs expressed higher levels of the known B cell growth factors IL-6, IL-10, and B cell-activating factor in response to TLR7/8 stimulation, they were unable to enhance B cell responses in this system.
|

|
These data help decipher the different roles of PDCs and MDCs for modulating human B cell responses and can contribute to selection of specific TLR ligands as vaccine adjuvants.

19376580
|
Up-regulation of Blimp-1, XBP-1, IRF4, and AID genes, which are responsible for class-switch recombination and somatic hypermutation, was observed in VLP-activated B2 cells.
|
9 |
19376580
|
Stimulation of naïve splenocytes with VLPs led to a high expression of IL-12, RANTES and MIP, the cytokine milieu that favors B cell differentiation into IgG2a secreting cells.

Bcl6 and Blimp-1 are reciprocal and antagonistic regulators of T follicular helper cell differentiation.
|
12 |

|
We found that expression of the transcription factor Bcl6 in CD4+ T cells is both necessary and sufficient for in vivo T(FH) differentiation and T cell help to B cells in mice.
|
13 |
19608860
|
In contrast, the transcription factor Blimp-1, an antagonist of Bcl6, inhibits T(FH) differentiation and help, thereby preventing B cell germinal center and antibody responses.
|

|
These findings demonstrate that T(FH) cells are required for proper B cell responses in vivo and that Bcl6 and Blimp-1 play central but opposing roles in T(FH) differentiation.

We demonstrate that the Cox-2 selective small molecule inhibitors SC-58125 and NS-398 attenuate the production of human antibody isotypes including immunoglobulin M (IgM), IgG1, IgG2, IgG3 and IgG4.
|
24 |
20050331
|
In addition, inhibition of Cox-2 significantly reduced the generation of CD38+ IgM+ and CD38+ IgG+ antibody-secreting cells.
|
25 |
20050331
|
Interestingly, we discovered that inhibition of Cox-2 activity in normal human B cells severely reduced the messenger RNA and protein levels of the essential plasma cell transcription factor, Blimp-1.
|
26 |
20050331

These observations were mirrored in Cox-2-deficient mice, which had reduced CD138+ plasma cells and a near loss of Blimp-1 expression.

Constitutive STAT5 signaling in activated CD4(+) T cells selectively blocked T(FH) cell differentiation and GCs, and IL-2 signaling was a primary inducer of this pathway.
|
67 |
22271576
|
Conversely, STAT5-deficient CD4(+) T cells (mature STAT5(fl/fl) CD4(+) T cells transduced with a Cre-expressing vector) rapidly up-regulated Bcl6 expression and preferentially differentiated into T(FH) cells during T cell priming in vivo.
|
68 |

Phenotype and function of protective, CD4-independent CD8 T cell memory.
|
70 |
22948808
|
While the need for CD4 T cells in the generation of CD8 T cell memory has been well documented, the mechanism underlying their requirement remains unknown.
|
71 |
22948808
|
Here, we detail an immunization method capable of generating CD8 memory T cells that are indifferent to CD4 T cell help.
|
72 |
22948808
|
Using a subunit vaccination that combines polyIC and an agonistic CD40 antibody, we program protective CD4-independent CD8 T cell memory.
|
73 |
22948808
|
When cells generated by combined polyIC/CD40 immunization are compared to cells produced following a CD4-dependent vaccination, Listeria monocytogenes, they display dramatic differences, both phenotypically and functionally.
|
74 |
22948808
|
The memory cells generated in a CD4-deficient host by polyIC/CD40 immunization provide protection against secondary infectious challenge, whereas cells generated by LM immunization in the same environment do not.
|
75 |
22948808
|
Interestingly, combined polyIC/CD40 immunization generates long-term memory cells with low Blimp-1 and elevated Eomes expression despite high expression of Blimp-1 during the primary response.
|
76 |
22948808
|
The potency of combined polyIC/CD40 to elicit CD8+ T cell memory in the absence of CD4 T cells suggests that it could be considered as a vaccine adjuvant in clinical situations where CD4 responses/numbers are compromised.
|

23816303
|
In the present study, we have used isolated purified B cells and in vivo studies to demonstrate that αGalCer and RA initiate a regulated expression of several genes essential for B cell activation and differentiation, such as Pax-5, Blimp-1, IRF-4 and activation-induced cytidine deaminase (Aid).
|
78 |
23816303
|
Moreover, whereas αGalCer mainly increased the expression of Pax-5, CD40 and CD86 that are critical for B cell activation, RA predominantly increased CD138⁺ and Fas⁺-PNA⁺ B cells, which represent more advanced B cell differentiation.

In this study, we took advantage of the low-inflammation model of dendritic cell immunization to study the role of the IL-2/Blimp-1 axis in SLEC differentiation as well as the importance of Blimp-1 expression in memory precursor effector cells for proper CD8(+) memory generation.
|
109 |
25015830

In addition, modulation of the bioavailability of IL-2 by injection either of a blocking Ab or of the cytokine, demonstrates a link between IL-2, Blimp-1 induction, and SLEC formation in wild-type cells.
|
110 |
25015830

Conversely, injection of IL-2 had less effect on Blimp-1-deficient CD8(+) T cells, indicating that the effect of IL-2 on in vivo SLEC differentiation is mediated by Blimp-1.

In addition, modulation of the bioavailability of IL-2 by injection either of a blocking Ab or of the cytokine, demonstrates a link between IL-2, Blimp-1 induction, and SLEC formation in wild-type cells.

|
Conversely, injection of IL-2 had less effect on Blimp-1-deficient CD8(+) T cells, indicating that the effect of IL-2 on in vivo SLEC differentiation is mediated by Blimp-1.

Mimicked acetylation of the Bcl6 middle domain (K379Q) in CD4 T cells results in significant reductions in Tfh differentiation in vivo.
|
144 |
26460037
|
Although Bcl6 K379Q still bound to the Prdm1 cis-regulatory elements in Tfh cells, Prdm1 expression was derepressed.
|
145 |
26460037
|
This was a result of the failure of Bcl6 K379Q to recruit metastasis-associated protein 3 (MTA3).
|
146 |
26460037
|
The loss of Bcl6 function in Bcl6 K379Q-expressing CD4 T cells could be partially rescued by abrogating Prdm1 expression.
|
147 |
26460037
|
In addition to Prdm1, we found that Bcl6 recruits MTA3 to multiple genes involved in Tfh cell biology, including genes important for cell migration, cell survival, and alternative differentiation pathways.
|
148 |

|
Thus, Bcl6 middle domain mediated repression is a major mechanism of action by which Bcl6 controls CD4 T-cell fate and function.
