The heterogeneity of CD4+ T cells has been investigated since the late 1970s, when their Th1 and Th2 subsets were coined. Later studies on the cutaneous form of the Leishmaniasis were focused on the experimental models of Leishmania major infection using the susceptible BALB/c and the resistant C57BL/6 mice. At the early 21st century, the regulatory T-cells subpopulation was introduced and its ...
background : nonmyeloablative chemotherapy followed by adoptive immunotherapy is an attractive strategy for depleting regulatory t cells in the host. however, its efficacy is transient. here, we aim to investigate whether cyclic chemoim- munotherapy has therapeutic efficacy against cancer. methods :we examined the efficacy of cyclic chemoimmunotherapy with cyclophos- phamide and adoptively tran...
Pulmonary metastasis of breast cancer requires recruitment and expansion of T-regulatory cells (Treg) that promote escape from host protective immune cells. However, it remains unclear precisely how tumors recruit Tregs to support metastatic growth. Here we report the mechanistic involvement of a unique and previously undescribed subset of regulatory B cells. These cells, designated tumor-evoke...
Asthma is characterized by T helper cell 2 (Th2) type inflammation, leading to airway hyperresponsiveness and tissue remodeling. Th2 cell-driven inflammation is likely to represent an abnormal response to harmless airborne particles. These reactions are normally suppressed by regulatory T cells, which maintain airway tolerance. The anti-inflammatory cytokine IL-10 is likely to play a central ro...
Regulatory T cells are important for ensuring that the immune system does not attack self and does not overreact to external antigens. Understanding how these cells develop and maintain stable function provides general insights into cellular differentiation in general, as well as new opportunities for therapeutic manipulation.
