Abstract
Previous evaluation of lymphocytes taken from patients with Wiskott-Aldrich syndrome (WAS) and other X-linked immunodeficiencies has revealed deficiencies of a lymphocyte sialoglycoprotein with a relative molecular mass of 115 kD (designated gpL-115) found in normal lymphocytes. The development of monoclonal antibodies to gpL-115 has permitted the detection of molecular heterogeneity in gpL-115 from the lymphocytes of immunodeficient patients. When lymphocytes from normal individuals were analyzed by immunoblotting, gpL-115 with only a single molecular species (115 kD) was detected. Lymphocytes from 17 immunodeficient patients were analyzed after overnight incubation. Two patients had no gpL-115 with an Mr of 115 kD, but gpL-115 with an Mr of either 95 or 135 kD was detected. Nine patients had gpL-115 with Mr equally of 95 and 115 Kd. Other patients exhibited gpL-115 with combinations of 95, 115, and 135 kD. The heterogeneity of the degraded gpL-115 suggests that WAS and other X-linked immunodeficiencies are due to a series of abnormalities, all of which involve gpL-115, and may explain the clinical heterogeneity of the diseases.

Usage information is collected from two different sources: this site (JCI) and Pubmed Central (PMC). JCI information (compiled daily) shows human readership based on methods we employ to screen out robotic usage. PMC information (aggregated monthly) is also similarly screened of robotic usage.
Various methods are used to distinguish robotic usage. For example, Google automatically scans articles to add to its search index and identifies itself as robotic; other services might not clearly identify themselves as robotic, or they are new or unknown as robotic. Because this activity can be misinterpreted as human readership, data may be re-processed periodically to reflect an improved understanding of robotic activity. Because of these factors, readers should consider usage information illustrative but subject to change.
