amongst affected individuals. To date, research of pathogenic mechanisms has largely been focused on processes involving
T lymphocyte and/or myeloid leukocyte populations. Involvement of B lymphocytes has received relatively little attention. In
contrast, B-cell pathobiology is a major field within general immunological research, and large clinical trials have showed that
treatments targeting B cells are highly effective for multiple systemic inflammatory diseases. B cells, including the terminally
differentiated plasma cell that produces antibody, are found in the human eye in different forms of non-infectious uveitis; in
some cases, these cells outnumber other leukocyte subsets. Recent case reports and small case series suggest that B-cell
blockade may be therapeutic for patients with non-infectious uveitis. As well as secretion of antibody, B cells may promote
intraocular inflammation by presentation of antigen to T cells, production of multiple inflammatory cytokines and support of
T-cell survival. B cells may also perform various immunomodulatory activities within the eye. This translational review
summarizes the evidence for B-cell involvement in non-infectious uveitis, and considers the potential contributions of B cells to
the development and control of the disease. Manipulations of B cells and/or their products are promising new approaches to the
treatment of non-infectious uveitis
