Utente:Armin6/Linfociti T gamma delta

I linfociti gamma delta (o linfociti γδ ) sono linfociti T caratterizzati da un TCR (recettore delle cellule T) di membrana diverso dai linfociti alfa e beta. are T cells that have a distinctive T-cell receptor (TCR) on their surface. Most T cells are αβ (alpha beta) T cells with TCR composed of two glycoprotein chains called α (alpha) and β (beta) TCR chains. In contrast, gamma delta (γδ) T cells have a TCR that is made up of one γ (gamma) chain and one δ (delta) chain. This group of T cells is usually much less common than αβ T cells, but are at their highest abundance in the gut mucosa, within a population of lymphocytes known as intraepithelial lymphocytes (IELs).
