Tumor-Specific CD4+ T Cells Restrain Established Metastatic Melanoma by Developing Into Cytotoxic CD4– T Cells

Frontiers in Immunology, 2022
Cytotoxic CD8+ T cells are the main focus of efforts to understand anti-tumor immunity and immunotherapy. The adoptive transfer of tumor-reactive cytotoxic CD8+ T lymphocytes expanded and differentiated in vitro has long been considered the primary ...

Human CD4 memory T cells can become CD4+IL-9+ T cells. [PDF]

PLoS ONE, 2010
IL-9 is a growth factor for T- and mast-cells that is secreted by human Th2 cells. We recently reported that IL-4+TGF-beta directs mouse CD4(+)CD25(-)CD62L(+) T cells to commit to inflammatory IL-9 producing CD4(+) T cells.Here we show that human ...

Circulating activated immune cells as a potential blood biomarkers of non-small cell lung cancer occurrence and progression

BMC Pulmonary Medicine, 2021
Background Treatment for non-small cell lung cancer (NSCLC) has greatly improved in recent years. However, noninvasive early screening for carcinogenesis and progression unclear.

Regulation and gene expression profiling of NKG2D positive human cytomegalovirus-primed CD4+ T-cells. [PDF]

PLoS ONE, 2012
NKG2D is a stimulatory receptor expressed by natural killer (NK) cells, CD8(+) T-cells, and γδ T-cells. NKG2D expression is normally absent from CD4(+) T-cells, however recently a subset of NKG2D(+) CD4(+) T-cells has been found, which is specific for ...

Metabolic features of naïve and memory CD4⁺T cells in quiescence and during proliferation

Acta Biomedica Scientifica, 2022
Background. Memory CD4+ T cells proliferation is the basis for accelerated secondary immune response. The characteristics of memory CD4+ T cells providing their faster division compared to naive CD4+ T lymphocytes are poorly understood.

CD4(+)CD62L(+) central memory T cells can be converted to Foxp3(+) T cells. [PDF]

PLoS ONE, 2013
The peripheral Foxp3(+) Treg pool consists of naturally arising Treg (nTreg) and adaptive Treg cells (iTreg). It is well known that naive CD4(+) T cells can be readily converted to Foxp3(+) iTreg in vitro, and memory CD4(+) T cells are resistant to ...

Failure of CD4 T-cells to respond to liver-derived antigen and to provide help to CD8 T-cells. [PDF]

PLoS ONE, 2011
CD4 T-cell help is required for the induction of efficient CD8 T-cells responses and the generation of memory cells. Lack of CD4 T-cell help may contribute to an exhausted CD8 phenotype and viral persistence.

T cell-specific P2RX7 favors lung parenchymal CD4+ T cell accumulation in response to severe lung infections

Cell Reports, 2023
Summary: CD4+ T cells are key components of the immune response during lung infections and can mediate protection against tuberculosis (TB) or influenza. However, CD4+ T cells can also promote lung pathology during these infections, making it unclear how

Memory T follicular helper CD4 T cells

Frontiers in Immunology, 2015
T follicular helper (Tfh) cells are the subset of CD4 T helper cells that are required for generation and maintenance of germinal center reactions and the generation of long-lived humoral immunity.

CD4+ primary T cells expressing HCV-core protein upregulate Foxp3 and IL-10, suppressing CD4 and CD8 T cells. [PDF]

PLoS ONE, 2014
Adaptive T cell responses are critical for controlling HCV infection. While there is clinical evidence of a relevant role for regulatory T cells in chronic HCV-infected patients, based on their increased number and function; mechanisms underlying such a ...
