SpletA dendritic cell that interacts with an already-activated helper T cell can become licensed. This occurs through the interaction of co-stimulatory molecules including B7 and CD40 on the dendritic cell, with CD28 and CD40 ligand on the T cell.

Prikaži več The T helper cells (Th cells), also known as CD4 cells or CD4-positive cells, are a type of T cell that play an important role in the adaptive immune system. They aid the activity of other immune cells by releasing cytokines. … Prikaži več In 1991, three groups reported discovering CD154, which is the molecular basis of T cell helper function. Seth Lederman at Columbia University generated … Prikaži več Historically, memory T cells were thought to belong to either the effector or central memory subtypes, each with their own distinguishing set … Prikaži več Th cells contain and release cytokines to aid other immune cells. Cytokines are small protein mediators that alter the behavior of target cells that express receptors for those cytokines.
