Unbalanced Neonatal CD4+ T-Cell Immunity [PDF]
In comparison to adults, newborns display a heightened susceptibility to pathogens and a propensity to develop allergic diseases. Particular properties of the neonatal immune system can account for this sensitivity. Indeed, a defect in developing protective Th1-type responses and a skewing toward Th2 immunity characterize today the neonatal T-cell ...

During an immune reaction, some antigen-experienced CD4 T cells relocate from secondary lymphoid organs (SLOs) to the bone marrow (BM) in a CD49b-dependent manner and reside and rest there as professional memory CD4 T cells.

Background After peripheral nerve transection, facial motoneuron (FMN) survival depends on an intact CD4+ T cell population and a central source of interleukin-10 (IL-10). However, it has not been determined previously whether CD4+ T cells participate in

STAT5 and CD4+ T Cell Immunity [PDF]
STAT5 plays a critical role in the development and function of many cell types. Here, we review the role of STAT5 in the development of T lymphocytes in the thymus and its subsequent role in the differentiation of distinct CD4+helper and regulatory T-cell subsets.

Distinct susceptibility of HIV vaccine vector-induced CD4 T cells to HIV infection. [PDF]
The concerns raised from adenovirus 5 (Ad5)-based HIV vaccine clinical trials, where excess HIV infections were observed in some vaccine recipients, have highlighted the importance of understanding host responses to vaccine vectors and the HIV ...

CD4+T Cells: Differentiation and Functions [PDF]
CD4+T cells are crucial in achieving a regulated effective immune response to pathogens. Naive CD4+T cells are activated after interaction with antigen-MHC complex and differentiate into specific subtypes depending mainly on the cytokine milieu of the microenvironment. Besides the classical T-helper 1 and T-helper 2, other subsets have been identified,

In vitro induction of regulatory CD4+CD8α+ T cells by TGF-β, IL-7 and IFN-γ. [PDF]
In vitro CD4(+) T cell differentiation systems have made important contributions to understanding the mechanisms underlying the differentiation of naive CD4(+) T cells into effector cells with distinct biological functions.

The type of responder T-cell has a significant impact in a human in vitro suppression assay. [PDF]
In type 1 diabetes (T1D), a prototypic autoimmune disease, effector T cells destroy beta cells. Normally, CD4(+)CD25(+high), or natural regulatory T cells (Tregs), counter this assault.

Summary: CD4 T cells are essential for immunity to tuberculosis because they produce cytokines, including interferon-γ. Whether CD4 T cells act as “helper” cells to promote optimal CD8 T cell responses during Mycobacterium tuberculosis is unknown.

Alteration of CD4CD25Foxp3 T cell level in Kawasaki disease [PDF]
PurposeExaggerated pro-inflammatory reactions during the acute phase of Kawasaki disease (KD) suggest the role of immune dysregulation in the pathogenesis of KD.
