2020.4.14 For decades, the omentum has been known as the policeman of the abdomen. Jackson-Jones et al. reveal the existence of specialized mesothelial cells within fat-associated lymphoid clusters of the omentum that are responsible for the capture of peritoneal contaminants via the formation of neutrophil aggregates, preventing systemic

2021.10.9 Lymphoid aggregates were encountered in 50% of living patients and 31% of autopsy bone marrows. As none of the patients had a history of hematolymphoid disease, and most of the aggregates were found in older decedents, these are likely non-neoplastic or so called “physiologic” aggregates [ 9 , 11 ].

Lymphoid aggregates (LA) develop during the proliferative phase of the menstrual cycle in the human uterine endometrium (EM). They contain mostly CD8 + T cells and B cells. As these LA are absent immediately following menses, they may arise by division of cells resident in the EM, or by division of a limited number of precursor cells that traffic into the
