Altered CD45 isoform expression affects lymphocyte function in CD45 Tg mice.
Transgenic mice have been constructed expressing high (CD45RABC) and low (CD45R0) molecular weight CD45 isoforms on a CD45-/- background. Phenotypic analysis and in vivo challenge of these mice with influenza and lymphocytic choriomeningitis viruses shows that T cell differentiation and peripheral T cell function are related to the level of CD45 expression but not to which CD45 isoform is expre...
متن کاملConfusion over Article 8
690 We enjoyed reading Andrea Rinaldi’s article, ‘Adopting an orphan’ (EMBO Rep 6: 507–510), on regulations that aim to stimulate the research and development of medicines for rare diseases. We would like to congratulate the author on the quality of the article in general and on highlighting this important health problem. However, Rinaldi stated that Emerging Biopharmaceutical Enterprises (EBE)...
متن کاملIndia combats confusion over counterfeit drugs.
India, the leading supplier of low-cost generic drugs to Africa, has begun fi ghting back to counter the confusion surrounding counterfeit drugs in the region. A raft of new and proposed anti-counterfeit laws could potentially deprive Africa of aff ordable, essential medicines. The immediate cause of concern is Kenya’s Anti-Counterfeit Act 2008, which came into eff ect in July, 2009. The new la...
متن کاملCD45 Isoform Expression in Microglia and Inflammatory Cells in HIV-1 Encephalitis
CD45 is a membrane tyrosine phosphatase that modulates the function of the hematopoietic cells. In vitro, agonist antibodies to CD45RO or CD45RB isoforms have been shown to suppress microglial activation, but whether microglia in vivo express these isoforms in HIV encephalitis (HIVE) is unknown. Brain sections from control and HIVE were immunostained for CD45 isoforms using exon-specific antibo...
متن کاملCD4+ T cell hyper-responsiveness in CD45 transgenic mice is independent of isoform.
The CD45 tyrosine phosphatase is required for T cell development and function by virtue of its role as a positive regulator of src family kinase activity. In addition, recent data have highlighted that CD45 also acts as a negative regulator of Lck function by dephosphorylation of critical tyrosine residues. Lck functionality and TCR responsiveness are elevated in transgenic mice expressing the ...
