Natural Tregs (D4+CD25+)
Summary CD4+CD25+ T cells arise during the normal process of maturation in the thymus and survive in the periphery as Treg cells. They constitute about 5-10% of in the periphery and…
generation of T regs
T regs similar to Th1 and Th2 cells, arise from naive precursors and can be differentiated in vitro. Effects of Cytokines In the case of murine , it has been shown…
regulatory T cells
It is now widely accepted that several types of regulatory cells exist, some of which are induced in response to infectious challenge and some that are considered natural regulators. Regulatory…
Memory T cells
In contrast to naive T cells, Memory/effector cells migrate mostly through peripheral tissues. This migration mediates rapid protective responses and is controlled by the expression of different sets of integrins…
CD4+ T helper cells
Types of T helper cells T helper cells (CD4+ T helper cells) can be divided into two major subsets termed , based on their pattern of secreted cytokines. T cells expressing…
T cells
Introduction: T cells are immune cells capable of responding to intracellular antigens, for example, dervied from infections or cancerous mutations. T-cell antigen recognition relies on a T-cell receptor (TCR) that…
lymphocytes
Lymphoctyes are one of many types of white blood cells produced in the bone marrow during hematopoiesis (The other white blood cells or "leukocytes" being neutrophils, monocytes, eosinophils and basophils).…
DC surface markers
The molecules expressed by human DCs can be divided into receptors for antigen uptake, such as TLRs, RcR, CD46, CD150 and C-type lectins, such as DC-specific ICAM-3-grabbing nonintegrin (DC-SIGN) migration…
plasmacytoid DCs
Introduction/Difference Plasmacytoid DC with Myeloid DCs: The two major subsets of human DCs, myeloid and plasmacytoid DCs (mDCs and pDCs, respectively) both have antigenpresenting capacity although mDCs are generally considered…
