Thymus and fetal liver implants to reconstitute T- and B-cell function have met with some success. (medscape.com)
αβ and γδ T cells are commonly thought to arise from a common precursor within the thymus gland yet perform distinct roles in pathogen resistance. (zist-fan.ir)
Though conventional αβ T cells depart the thymus in a naïve state and acquire effector function in the periphery, the effector fate of many γδ T cells is defined in the thymus, and they exhibit limited plasticity after that. (zist-fan.ir)

T helper (Th) 2 cells, which recruit and accumulate in the lungs and produce a range of different effector cytokines. (cdc.gov)
However, more recent studies have revealed the potential collaboration of other helper T cells and their cytokines in this process. (cdc.gov)
The aim of this review is to summarize the current knowledge about the possible roles of newly identified helper T cells derived cytokines (IL-9, 17, 22, 25 and IL-33) in asthma. (cdc.gov)

However, broad and robust memory CD4 + and CD8 + T cells persist for longer periods in convalescent patients and may mediate resistance to reinfection [ 12 ]. (aging-us.com)

Functional analysis showed that ILT2+CD56dimNK cells in CHB patients had significantly reduced degranulation and IFN-Î³ production. (bvsalud.org)
A 2013 study by Elahi demonstrated that infant immune cells are fully functional, but are temporarily inhibited during the first two years of life. (honeycolony.com)
The development of clinically applicable methods to produce large numbers of fully functional NK cells is a critical step to maximize the potential of this approach. (aacrjournals.org)

The CD4 + coreceptor is expressed by helper T cells and helps bind to class II MHC. (nanoteintech.com)

While immune checkpoint inhibitors are very effective in cancer treatment, their effect is not only limited to tumor cell and they have many autoimmune side effects. (cuanschutz.edu)
She is currently engaged in efforts to identify allosteric inhibitors of ITK that could be used in combination with active site kinase inhibitors to target ITK and thereby interfere with autoimmune T cell infiltration. (cuanschutz.edu)

However, HLA-identical sibling stem cell infusions in ADA-SCID result in some donor stem cell engraftment and long-term thymopoiesis. (frontiersin.org)

RT-induced damage to cancer cells leads to different outcomes, such as survival, senescence, or death. (nature.com)
In this review, we discuss the changes in irradiated cancer cells and immune cells in the TME under different RT regimens and describe existing and potential molecules that could be targeted to improve the therapeutic effects of RT. (nature.com)
Technologically when DC manipulates the tumor antigen under the most favorable conditions in vitro, DC then becomes a vaccine carrying tumor antigen and ready for injecting to the patient to re-simulates or re-activate s cancer killer T cells ability to suppress the grow of cancer. (safesavecell.com)
ADCTA is able to kill the remaining cancer cells to has a significant result of increasing Overall Survival, OS Rate while the conventional chemotherapy or radiotherapy is applied at the same time. (safesavecell.com)
