Is m2-polarized tumor-associated macrophage infiltration of regional lymph nodes associated with nodal lymphangiogenesis and occult nodal involvement in pN0 pancreatic cancer?
M2-polarized TAM infiltration of RLNs is significantly associated with nodal lymphangiogenesis and occult nodal involvement in pN0 pancreatic cancer. Node-infiltrating M2-polarized TAMs may facilitate nodal lymphangiogenesis via the production of vascular endothelial growth factor C and thus promote RLN metastasis.
Telomerase activity in PBMCs is reduced in HD patients. It seems that, at least in this type of cell in this population, defense from senescence, as assessed by telomerase activity, is altered and associated with the chronicity of uremia/HD procedure.
