Toll-like receptor activity patterns have been globally studied considering immune biomarkers in breast tumors in a multicentric proteome study (105) with a clear clinical goal, but comprehensive basic studies have also been performed in relation to the activity of cancer-associated fibroblasts’ presence and absence (106), immune escape by GATA3 destabilization (107), and follicular helper cells as promoters of effective adaptive immunity (108). The gene discussed is GATA3; the disease is breast neoplasm.
