We analyzed Ki-67 indices, the expression status of CD54 and its receptor (CD11a), and the intercellular distance of tumor cells in 40 diffuse large B-cell lymphoma (DLBCL) cases with vascular invasion to analyze the association of cell adhesion and proliferation status. CD54 and CD11a were simultaneously expressed (double-positive) in extra/intravascular tumor cells in 14 (35%) of the cases. Histologically, lymphoma cells of the double positive cases exhibited significantly higher Ki-67 index in extravascular tumor cells than that in the intravascular ones, while no difference was observed in lymphoma cells of the non-double positive cases. The significantly shorter extravascular intercellular distance compared with the intravascular intercellular distance suggested the association between cell-cell adhesion mediated by CD54 and cell proliferation. We further confirmed that the treatment of the recombinant LFA1 (CD11a/CD18) showed the adhesion of human DLBCL-derived cell line HBL-2 to LFA1 and increased cell viability. These findings suggest that cell-to-cell adhesion via CD54 maintains the cell proliferative activity of a subset of DLBCL.

Macrophages (Mφs), a type of stromal cell, are transformed into tumor-associated Mφs (TAMs) after integrating within solid tumors. TAMs are known to interact with cancer cells and induce tumor progression. Thus, the cancer cells construct an organ-specific TME, which is advantageous for the survival of cancer cells in the TME. The density of stromal cells is known to be involved in the prognosis of patients with lymphomas. A higher density of stromal cells increases the interaction between lymphoma cells and stromal cells, promoting lymphoma progression. This review focuses on stromal cells in lymphoid tissues, such as TAMs, fibroblastic reticular cells (FRCs), and follicular dendritic cells (FDCs). This review also focuses on the signal transduction caused by stromal cells and tumor cells via factors such as cytokines. IL-10 and other cytokines secreted by TAMs activate the JAK/STAT pathway in lymphoma cells of follicular lymphoma, classic Hodgkin lymphoma, and diffuse large B-cell lymphoma. FRCs play roles in tumor promotion in follicular lymphoma and diffuse large B-cell lymphoma. Cytokines/chemokines secreted by FDCs play essential roles in lymphoma cell survival, proliferation, invasion, and migration in follicular lymphoma. In conclusion, TAMs, FRCs, and FDCs play crucial roles in the TME of lymphomas. Furthermore, histological spatial analysis revealing the positional relationship of each cell could highlight lymphoma-stromal interactions.</p>","PeriodicalId":45936,"journal":{"name":"Journal of Clinical and Experimental Hematopathology","volume":" ","pages":"166-176"},"PeriodicalIF":0.9,"publicationDate":"2024-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11528246/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141861201","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
