Functional T cell immunodeficiency characterized by defective TCR/CD3 induced tyrosylphosphorylation.
Defective T cell activation has been recognized in a number of patients with primary immunodeficiencies (ID). A distal defect resulting in abnormal production of IL2, IL3, IL4 and IFN gamma was found to be associated with reduced binding of the NF-AT transcription factor to the promoters of the genes coding for these lymphokines. Defect in early steps of T cell activation have been described in primary IDs, consisting in defective calcium flux and phosphoinositides turnover following TCR/CD3 ligation. We herein report a primary ID found in a 13 year old girl. It consists in a partially defective T cell proliferation which could be related to a defective Tyrosine phosphorylation.
