What is "centrocyte"

n. (context anatomy English) Any follicular center cell that has a cleft

A centrocyte generally refers to a B cell with a cleaved nucleus, as may appear in e.g. follicular lymphoma.

During B cell development, centrocytes are formed following the cessation of centroblast proliferation. Centrocytes test their newly mutated anti-binding sites ( CDR loops) by re-expressing antigen on their surface.

Centrocyte can also refer to a cell with a protoplasm that contains single and double granules of varying size stainable with hematoxylin, as seen in lesions of lichen planus, or a nondividing, activated B cell that expresses membrane immunoglobulin.
