T cell differentiation, effector pathways, and related primary immunodeficiencies (PIDs). Hematopoietic stem cells (HSCs) differentiate into common lymphoid progenitors (CLPs), which, in turn, give rise to the T cell precursors that migrate to the thymus. The development of CD4+ and CD8+ T cells is shown. Known T cell effector pathways are indicated, that is, γδ cells, cytotoxic T cells (Tc), TH1, TH2, TH17, TFh (follicular helper) CD4 effector T cells, regulatory T cells (Treg), and natural killer T cells (NKTs); abbreviations for PIDs are contained in boxes. Vertical bars indicate a complete deficiency; broken bars a partial deficiency. SCID, severe combined immunodeficiency; ZAP 70, zeta-associated protein deficiency, MHCII, major histocompatibility complex class II deficiency; TAP, TAP1 and 2 deficiencies; Orai1, Stim1 deficiencies; HLH, hematopoietic lymphohistiocytosis; MSMD, Mendelian susceptibility to mycobacterial disease; Tyk2, DOCK8, autosomal recessive form of hyper-IgE syndrome; STAT3, autosomal dominant form of hyper-IgE syndrome; CD40L, ICOS, SAP deficiencies; IPEX, immunodysregulation polyendocrinopathy enteropathy X-linked syndrome; XLP, X-linked proliferative syndromes.
