A genetic variant of the protein tyrosine phosphatase non-receptor 22 (PTPN22) is associated with a wide range of autoimmune diseases; however, the reasons behind its prevalence in the general population remain not completely understood. Recent evidence highlights an important role of autoimmune

PTPN22 (protein tyrosine phosphatase non receptor 22) encodes a tyrosine phosphatase that functions as a key regulator of immune homeostasis. In particular, PTPN22 inhibits T-cell receptor signaling and selectively promotes type I interferon responses in myeloid cells. To date, there is little
Normal B lymphocyte development but impaired T cell maturation in CD45-exon6 protein tyrosine phosphatase-deficient mice.

The transmembrane tyrosine phosphatase CD45 is expressed in multiple isoforms on all nucleated hematopoietic cells, resulting from alternative splicing of variable exons. We generated mice with a mutation in the variable CD45 exon 6, using homologous recombination. In mice homozygous for the
T cell-mediated hepatitis in mice infected with lymphocytic choriomeningitis virus. Liver cell destruction by H-2 class I-restricted virus-specific cytotoxic T cells as a physiological correlate of the 51Cr-release assay?

A model for immunologically T cell-mediated hepatitis was established in mice infected with lymphocytic choriomeningitis virus (LCMV). The severity of hepatitis was monitored histologically and by determination of changes in serum levels of the enzymes alanine aminotransferase (ALT), aspartate

Mitogen-activated protein (MAP) kinases are essential regulators in immune responses, and their activities are modulated by kinases and phosphatases. MAP kinase phosphatase (MKP) is a family of dual-specificity phosphatases whose function is evolutionarily conserved. A number of mammalian MKPs have

During an autoimmune process, the autoaggressive response spreads from the initiating autoantigen to other antigens expressed in the target organ. Based on evidence from experimental models for multiple sclerosis, such "antigenic spreading" can play an important role in the exacerbation of clinical
Alterations in the level of CD45 surface expression affect the outcome of thymic selection.

CD45 is a receptor protein tyrosine phosphatase whose activity is required for thymocyte development and TCR-mediated signal transduction. Here we show that positive selection of TCR-alphabeta transgenic thymocytes is completely blocked in CD45 exon 6 -/- gene-deficient (CD45 -/-) mice that express

One mechanism viruses use to subvert immune surveillance is through mutation of MHC contact residues of antigenic epitopes that weaken T cell recognition to the point that the immune system is ignorant of the infection. However, in contrast to ignorance, results presented herein demonstrate that
CD45 is required for type I IFN production by dendritic cells.

CD45 is a leukocyte tyrosine phosphatase, essential for normal immune responses. We have studied the function of splenic dendritic cells of CD45(+/+), CD45(-/-), CD45RABC and CD45RO transgenic mice. We show that there are increased numbers of plasmacytoid dendritic cells in CD45(-/-) mice. DC of all
