IL-33-ILC2 axis in the female reproductive tract.

Trends Mol Med 2022 May 12. Epub 2022 May 12.

Department of Biomedical and Molecular Sciences, Queen's University, Kingston, ON K7L 2V5, Canada. Electronic address:

IL-33 is a member of the IL-1 family and was first identified as an alarmin that acts at mucosal barrier sites. However, IL-33 is now understood to be a pleiotropic cytokine that acts on a variety of immune and non-immune cell types to promote type 2 T helper cell (T2) inflammation as well as to regulate and suppress homeostatic processes. Of particular interest are group 2 innate lymphoid cells (ILC2s) which are activated by IL-33 and promote many IL-33-specific effects. Read More

Gene Expression of Pregnancy Neutrophils Differs for Protease versus Lipopolysaccharide Stimulation.

Int J Mol Sci 2022 Apr 28;23(9). Epub 2022 Apr 28.

Department of Obstetrics and Gynecology, Virginia Commonwealth University, Richmond, VA 23298-0034, USA.

Neutrophils, which extensively infiltrate maternal systemic blood vessels in preeclampsia, express protease-activated receptor 1 (PAR-1) but only during pregnancy. Neutrophils are generally considered to be non-specific in their response, but the pregnancy-specific expression of PAR-1 could result in a gene expression profile unique to pregnancy, which could help explain why the maternal inflammatory response in preeclampsia is systemic rather than localized. We sought to determine if gene expression of pregnancy neutrophils would differ if stimulated by a protease versus bacterial lipopolysaccharide (LPS). Read More
