The project aims to investigate whether there are any phenotypical differences based on the expression of CD16, CD62L, CD184, CD11b, CD36, and CD47 between tumour-associated neutrophils (TANs), neutrophils in TDLNs, non-TDLNs in patients with OSCC as well as in lymph nodes coming from the neck of patients without cancer. Here, ITGAM is linked to neoplasm.
