gammadelta T cell (γδ T cell)

gammadelta T cell [ENGLISH]

Gamma delta T cells (γδ T cells) are T cells that have a γδ 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, 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 less common than αβ T cells. Their highest abundance is in the gut mucosa, within a population of lymphocytes known as intraepithelial lymphocytes (IELs).

gammadelta T cell [SWEDISH]

γδ-T-celler, (gamma-delta-T-celler) utgör en liten del av T-cellerna, och har en speciell typ av T-cellsreceptor (TCR) på sin yta. En majoritet av T-cellerna har en TCR bestående av två glykoproteinkedjor, α- och β-TCR. Men i γδ T-celler består T-cellsreceptorn av en γ-kedja och en δ-kedja. Denna grupp av T-celler är mycket ovanligare (5 % av det totala antalet T-celler) än αβ T-celler, och förekommer främst i tarmen, i en grupp av lymfocyter som kallas intraepiteliala lymphocyter (IEL:s).
