Defects in Innate Immunity
Disease | Affected Cell | Functional Defect | Associated Features | Inheritance | Gene Defect/Presumed pathogenesis |
---|---|---|---|---|---|
Anhidrotic ectodermal dysplasia with immunodeficiency (EDA-ID) | Lymphocytes + Monocytes | NFκB signalling pathway | anhidrotic ectodermal dysplasia + specific antibody deficiency (lack of Ab response to polysaccharides) various infections (mycobacteria and pyogens) | XR | Mutations of NEMO (IKBKG), a modulator of NF-κB activation |
Anhidrotic ectodermal dysplasia with immunodeficiency (EDA-ID) | Lymphocytes + Monocytes | NFκB signalling pathway | anhidrotic ectodermal dysplasia + T cell defect + various infections | AD | Gain-of-function mutation of IKBA, resulting in impaired activation of NF-κB |
Interleukin-1 Receptor Associated kinase 4 (IRAK4) deficiency | Lymphocytes + Monocytes | TIR-IRAK signalling patwhay | Bacterial infections (pyogens) | AR | Mutation of IRAK4, a component of TLR-signaling pathway |
WHIM (Warts, Hypogammaglobulinemia infections,Myelokathexis) syndrome | Granulocytes + Lymphocytes | Increased response of the CXCR4 chemokine receptor to its ligand CXCL12 (SDF-1) | Hypogammaglobulinemia, reduced B cell number, severe reduction of neutrophil count, warts/HPV infection | AD | Gain-of-function mutations of CXCR4, the receptor for CXCL12 |
Epidermodysplasia verruciformis | Keratinocytes and leukocytes | ? | Human Papilloma virus (group B1) infections and cancer of the skin | AR | Mutations of EVER1, EVER2 |
Herpes simplex encephalitis (HSE) | Central nervous system resident cells, epithelial cells and leukocytes | UNC-93B-dependent IFN-α, -β, and –γ induction | Herpes simplex virus 1 encephalitis and meningitis | AR | Mutations of UNC93B1 |
Herpes simplex encephalitis (HSE) | Central nervous system resident cells, epithelial cells, dendritic cells, cytotoxic lymphocytes | TLR3-dependent IFN-α, -β, and –γ induction | Herpes simplex virus 1 encephalitis and meningitis | AD | Mutations of TLR3 |
NF-κB: nuclear factor Kappa B; TIR: Toll and Interleukin 1 Receptor; HPV: human papilloma virus; TLR: Toll-like receptor
