Peripheral Blood Lymphocyte Cell Surface Markers during the Course of Systemic Lupus Erythematosus

Abstract

Peripheral blood lymphocytes from 23 patients with active systemic lupus erythematosus (SLE) were serially studied. Changes in bone marrow-derived lymphocytes (B cells), as measured by surface Ig receptors and C3 receptors, and in thymus-derived cells (T cells) measured by rabbit T-cell-specific antiserum and E-binding techniques, were correlated with fluctuations in clinical disease activity and treatment. In normal controls B- and T-cell percentages remained relatively stable, although the situation in SLE was much more labile. A relative and absolute decrease in T lymphocytes and cells bearing a receptor for C3 was found in active lupus. Absolute numbers of cells bearing surface Ig were decreased to a lesser extent, whereas the proportion of these cells was increased. It is postulated that the increase in autoantibody formation and diminished delayed hypersensitivity seen in systemic lupus may be due to a loss of T-lymphocyte function.

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.
