21. Plasma cells are short-lived cells ( 2 3 days ) that secrete antibodies.22. Plasma cell gingivitis may also occur, which may be accompanied by glossitis and cheilitis.23. Chim et al . demonstrated simultaneous expression of Wz and Fzd in myeloma plasma cells . 24. Plasma cell cheilitis appears as well defined, infiltrated, dark red atrophic and fissured.25. Plasma cells and fibrosis increase in later stages with the former being numerous and prominent.26. Plasma cells can only produce a single kind of antibody in a single class of immunoglobulin.27. The proteins are immunoglobulin light chains ( paraproteins ) and are produced by neoplastic plasma cells . 28. In his later years, Boros suffered from multiple myeloma, a cancer of plasma cells . 29. This receptor is normally expressed by melanocytes, plasma cells and skin-homing T cells. 30.
