CD40 and CD154 (CD40 ligand) are surface molecules that are central to the cross-talk between T cells and antigen-presenting cells. This article reviews the relevance of CD40-CD154 interaction for regulation of interleukin-12/interferon-gamma production in response to Toxoplasma gondii as an example of an intracellular pathogen. The manner in which defects in CD154 signaling contribute to immun...
The activation-induced cytidine deaminase (AID) gene, specifically expressed in germinal center B cells in mice, is a member of the cytidine deaminase family. We herein report mutations in the human counterpart of AID in patients with the autosomal recessive form of hyper-IgM syndrome (HIGM2). Three major abnormalities characterize AID deficiency: (1) the absence of immunoglobulin class switch ...
in vitro fertilization (ivf) and other assisted reproductive technologies present an enormous hope to couples with fertility difficulties. assisted reproductive technology is one of the risk factors that can result in anxiety in these couples. indeed, ivf-treatments cause a stress, for both the woman and her partner. the different stages of the ivf-procedure can affect the emotional life of the...
The hyper-IgE syndromes are rare, complex primary immunodeficiencies characterized by clinical manifestation diversity, by particular susceptibility to staphylococcal and mycotic infections as well as by a heterogeneous genetic origin. Two distinct entities--the classical hyper-IgE syndrome which is inherited in an autosomal dominant pattern and the autosomal recessive hyper-IgE syndrome--have ...
Severe combined immunodeficiency (SCID) and X-linked agammaglobulinemia (XLA) are inborn errors of immune function that require prompt diagnosis and treatment to prevent life-threatening infections. The lack of functional T or B lymphocytes in these diseases serves as a diagnostic criterion and can be applied to neonatal screening. A robust triplex PCR method for quantitation of T-cell receptor...
