Abstract

Transient receptor potential melastatin 8 (TRPM8) is a member of the transient receptor potential superfamily of Ca2+ channels. The aim of the present study was to clarify TRPM8 expression in reactive lymphoid tissues and mature B‑cell neoplasms. Reactive and neoplastic lymphoid tissues were used to evaluate TRPM8 expression by immunohistochemistry and reverse transcription‑polymerase chain reaction (RT‑PCR). TRPM8+ cells were frequently detected in the follicular light zone and marginal zone of reactive lymphoid tissues. Double immunostaining revealed that TRPM8+ cells co‑expressed cluster of differentiation (CD) 38, CD79a, CD138, interferon regulatory factor 4/melanoma associated antigen (mutated) 1, B cell CLL/lymphoma 6 and transmembrane activator and CAML interactor. TRPM8+ neoplastic cells were frequently detected in plasma cell myeloma. The positive band of TRPM8 mRNA was confirmed by RT‑PCR in cases of myeloma. The present study is, to the best of our knowledge, the first to demonstrate the expression of TRPM8 in reactive lymphoid tissues and mature B‑cell neoplasms, revealing that TRPM8 is frequently expressed in pre‑plasmablasts, plasmablasts, plasma cells and mature B‑cell lymphomas that are likely to differentiate into plasma cells.
