Lymphocytes and transplantation immunity.

摘要: Publisher Summary This chapter discusses different aspects of transplantation immunity and presents complete review the lymphocyte its role in types immunological reactions experimental animals vitro systems. The lymphoid tissues a normal mammal constitute about 1% body weight predominant cellular component is “small” lymphocyte. Lymphocytes serve as trephocytes stem cells even regulators tissue growth size. On basis their morphology size, lymphocytes are subdivided into “large,” “medium,” varieties. majority present within well blood lymph variety. large medium categories represent much more heterogeneous population cells, some which possess strongly basophilic cytoplasm. Electron microscope studies ultrastructure these reveals two types, both distinguishable from small on cytoplasmic organelles abundant Among characteristics lymphocytes, ubiquity, mobility, longevity desirable attributes any cell type to participate recognition, effector, memory phenomena. recirculating rather than sessile population, play an important primary response rats skin homografts.
