IL-23 and IL-12 are heterodimeric cytokines which share the p40 subunit, but which have unique second subunits, IL-23p19 and IL-12p35. Since p40 is required for the development of the Th1 type response necessary for resistance to Toxoplasma gondii, studies were performed to assess the role of IL-23 in resistance to this pathogen. Increased levels of IL-23 were detected in mice infected with T. ...

Psoriasis is a chronic, immune-mediated disease affecting more than 100 million people worldwide and up to 2.2% of the UK population. The aetiology of psoriasis is thought to originate from an interplay of genetic, environmental, infectious and lifestyle factors. The manner in which genetic and environmental factors interact to contribute to the molecular disease mechanisms has remained elusive...

BACKGROUND Uveitis is an eye inflammatory disease, which is sometimes associated with underlying systemic disease. Interleukin-23 plays an important role in autoimmune disease. The aim of this meta-analysis was to evaluate the association between the interleukin-23 receptor (IL-23R) and susceptibility to uveitis. METHODS Published literature from PUBMED and EMBASE were retrieved. Seven studie...

George Palade's pioneering work in the 1960s had established the secretory pathway and its connection to the biogenesis of organelles as a major theme in eukary-otic cell biology (Palade, 1975). His disciples, including David Sabatini and Gunter Blobel, extended Palade's morphological approaches to the next level of analysis, involving subcellular fractionation and biochemical re-constitution t...

Adolescents in the ninth grade (n=75) responded to a hypothetical situation involving an individual who neglects their friend as a result of their transition to steady dating. Results indicated that 53 per cent of girls and 32 per cent of boys reported past personal exclusion by their best friend who they perceived to be preoccupied by a romantic partner. Only 21 per cent of girls and 19 per ce...

A new efficient method for the synthesis of 2,3-dihydroquinazolin-4(1H)-ones and spiroquinazolinones via a condensation reaction of aldehydes and ketones with anthranilamide in the presence of nano Fe3O4@SiO2-SO3H as catalyst in ethanol has been described. The reactions are completed in short times, and the corresponding dihydroquinazolinones are produced with high yields. The present procedure...
