The Regulatory T Cell Family: Distinct Subsets and their Interrelations

The regulatory T cell family: distinct subsets and their interrelations.

Regulatory T Cell Subsets in Filarial Infection and Their Function

Filarial infections in humans are chronic infections that cause significant morbidity. The chronic nature of these infections with continuous antigen release is associated with a parasite-specific T cell hypo-responsiveness that may over time also affect the immune responses to bystander antigens. Previous studies have shown the filarial parasite antigen-specific T cells hypo-responsiveness is ...

CCR7 provides localized access to IL-2 and defines homeostatically distinct regulatory T cell subsets

Immune tolerance and activation depend on precise control over the number and function of immunosuppressive Foxp3(+) regulatory T (T reg) cells, and the importance of IL-2 in maintaining tolerance and preventing autoimmunity is clear. However, the homeostatic requirement for IL-2 among specific populations of peripheral T reg cells remains poorly understood. We show that IL-2 selectively mainta...

The birth of functionally distinct T cell subsets.

Neuropilin-1 distinguishes natural and inducible regulatory T cells among regulatory T cell subsets in vivo

Foxp3(+) CD4(+) T helper cells called regulatory T (T reg) cells play a key role in controlling reactivity to self-antigens and onset of autoimmunity. T reg cells either arise in thymus and are called natural T reg (nT reg) cells or are generated in the periphery through induction of Foxp3 and are called inducible T reg (iT reg) cells. The relative contributions of iT reg cells and nT reg cells...
