objectives: platelets are anucleated fragments derived from megakaryocytes. it has been demonstrated that platelets play a role in hemostasis and innate immunity. in addition, platelets have a cd40 ligand which is an important molecular marker in motivating immune cells. thus, platelets also have a role in adaptive immunity as seen by their ability to activate b cells. since human platelet micr...

Background: B cells can increase the expression of granzyme B in CD8+ T cells through 4-1BBL/4-1BB interaction and promote anti-tumor immunity. Objective: To investigate the expression of 4-1BBL on B cells in the breast tumor draining lymph nodes (TDLNs) and its association with disease parameters. Methods: Using Ficoll-Hypaque gradi...
