Lymphocyte population characterization in ovarian cancer microenvironment

Background: Ovarian cancer (OC) is one of the most common gynecological cancers, with poor prognosis and high mortality [1]. A key early sign of OC is the presence of ascites [2], indicating transcoelomic metastasis and tumor spread within the peritoneal cavity [3]. The accumulation of this serous fluid facilitates migration of tumor cells, which detach from the primary tumor (PT) in multicellular aggregates, m...

Immune microenvironment of the omentum in appendicitis: a phenotypic perspectiv...

Background: The omentum plays a crucial role in managing inflammation and combating infections, particularly in acute appendicitis [1]. This fat-rich fold of the peritoneum contains lymphoid structures known as “Milky Spots”, which house several types of phenotypically and functionally distinct immune cells, including macrophages and lymphocytes, that contribute to its protective function [1,2]. Among these, T ...

Omentum picture: unraveling the enigma of the immune microenvironment in append...

Background: Appendix obstruction triggers inflammation and exaggerated immune responses, leading the omentum, rich in Milky Spots (MS) housing immune cells, to play a vital role in peritoneal immunity. These MS collect antigens and pathogens, inducing immune responses like inflammation, immune tolerance, or fibrosis [1,2]. Their activities, including angiogenesis, stem cell differentiation, and immune resp...

Evaluating the impact of high sugar diet on juvenile rats: a histomorphological...

Background: Intestinal barrier is an important structure that defends and maintains the homeostasis of the host. [1-3]. It is highly influenced by food due to the interaction between nutrients and gut microbiota [2]. A diet rich in sugar can disrupt gut homeostasis, leading to a dysfunctional barrier and causing chronic diseases [3]. The enterochromaffin cells (ECs) are dispersed throughout the intestine wall, ...
