These results establish CtsW as an important host factor for entry of influenza A virus into target cells and suggest that CtsW could be a promising target for the development of future antiviral drugs.
The predominant expression of wildtype form by infiltrating immune cells was confirmed in 116 patients with gastroesophageal reflux disease and 27 reflux-negative individuals demonstrating that cathepsin W expression is not altered in this disease.
Cathepsin W-positive cells had a 'lymphocyte phenotype', but the relative portion of cathepsin W-positive cells among the infiltrating leukocytes in gastrointestinal disease differed remarkably.
a genetic variant and a novel isoform of cathepsin W are present in about 14% and 12%, respectively, within the Caucasian population
Despite being expressed in the effector subset of CD8 (show CD8A ELISA Kits)(+) and NK cells and of being released during target cell killing, our functional inhibition studies exclude an essential role of CatW in the process of cytotoxicity.
Endogenous cathepsin W is expressed predominantly in NK cells, is up-regulated by IL-2 (show IL2 ELISA Kits), and is mainly targeted to the endoplasmic reticulum.
The protein encoded by this gene, a member of the peptidase C1 family, is a cysteine proteinase that may have a specific function in the mechanism or regulation of T-cell cytolytic activity. The encoded protein is found associated with the membrane inside the endoplasmic reticulum of natural killer and cytotoxic T-cells. Expression of this gene is up-regulated by interleukin-2.
