Regulation of lymphocyte function by adenosine.
Adenosine regulates the interaction between lymphocytes and the vasculature, and is important for controlling lymphocyte trafficking in response to tissue injury or infection. Adenosine can blunt the effects of T cell receptor activation primarily by activating adenosine A(2A) receptors and signaling via cyclic AMP and protein kinase A. Protein kinase A reduces proximal T cell receptor signalin...
متن کاملRegulation of Inflammation by Adenosine
Adenosine, a purine nucleoside generated by the dephosphorylation of adenine nucleotides, is a potent endogenous physiologic and pharmacologic regulator of many functions. Adenosine was first reported to inhibit the inflammatory actions of neutrophils nearly 30 years ago and since then the role of adenosine and its receptors as feedback regulators of inflammation has been well established. Here...
متن کاملRegulation of epithelial and lymphocyte cell adhesion by adenosine deaminase-CD26 interaction.
The extra-enzymic function of cell-surface adenosine deaminase (ADA), an enzyme mainly localized in the cytosol but also found on the cell surface of monocytes, B cells and T cells, has lately been the subject of numerous studies. Cell-surface ADA is able to transduce co-stimulatory signals in T cells via its interaction with CD26, an integral membrane protein that acts as ADA-binding protein. ...
متن کاملAdenosine Receptors: Expression, Function and Regulation
Adenosine receptors (ARs) comprise a group of G protein-coupled receptors (GPCR) which mediate the physiological actions of adenosine. To date, four AR subtypes have been cloned and identified in different tissues. These receptors have distinct localization, signal transduction pathways and different means of regulation upon exposure to agonists. This review will describe the biochemical charac...
