General description
CD19 is present in both normal and malignant B-cells and has long been considered to be the most reliable surface marker of this lineage over a wide range of maturational stages. In normal lymphoid tissue, CD19 is observed in germinal centers, mantle zone cells, and scattered cells in the interfollicular areas. Anti-CD19 exhibits an overall immunoreactivity pattern similar to those of the antibodies against CD20 and CD22. However, in contrast to CD20, CD19 is also expressed in immature B-cells; although recent studies have described CD19 loss in a few B-cell neoplasms.

To clarify the clinicopathologic significance of a loss of CD19 expression in diffuse large B-cell lymphoma (DLBCL), we evaluated CD19 expression immunohistochemically in frozen sections from 227 patients who had received diagnoses of DLBCL according to the World Health Organization

Intrarenal B cell clusters are associated with poor clinical outcome in acute interstitial rejection. The incidence of B cell aggregates in vascular rejection and the effect of therapy with the monoclonal CD20 antibody rituximab on intrarenal B cells are currently

Previous immunohistochemical studies of muscle from patients with inclusion body myositis and polymyositis found many more T cells than B cells, suggesting a role for intramuscular cell-mediated immune mechanisms rather than humoral mechanisms. Microarray studies were performed on muscle biopsy
