Innate lymphoid cells expressing the nuclear hormone receptor RORC have emerged as important players in human mucosal immunity. These cells combine innate modes of activation such as Toll-like receptor signaling with secretion of adaptive effector molecules including IL-2, BAFF and the Th17 cytokines IL-17 and IL-22. This endows these cells with the ability to rapidly respond to changes in cytokine milieu as well as changes in microbial composition and to affect both intestinal homeostasis and activation of adaptive immune cells.

Type 2 innate lymphoid cells (ILC2s) mainly reside in tissues with few lymphoid cells. How their tissue residency is regulated remains poorly understood. This study explores the inhibitory role of SLAM-family receptors (SFRs) on adaptive immune cells in ILC2 maintenance.

Endometriosis is a gynecologic condition characterized by the growth of endometrium-like stroma and glandular elements outside of the uterine cavity. The involvement of hormonal dysregulation, specifically estrogen, is well established in the initiation, progression, and maintenance of the condition. Evidence also highlights the association between endometriosis and altered immune states.

Polycystic ovary syndrome (PCOS) affects 6%-10% of women of reproductive age and is known to be associated with disruptions in the gut bacteria. However, the role of the gut mycobiota in PCOS pathology remains unclear. Using culture-dependent and internal transcribed spacer 2 (ITS2)-sequencing methods, we discovered an enrichment of the gut-colonizable fungus Aspergillus tubingensis in 226 individuals, with or without PCOS, from 3 different geographical areas within China.

Allergic airway inflammation is a universal airway disease induced by inhaling allergens. Published data show that RNF128, an E3 ligase, promotes Th2 activation in the OVA-induced asthma model. Recent advances have shown that group 2 innate lymphoid cells (ILC2s) produce the cytokines IL-5 and IL-13 to mediate type 2 immune response.

The female genital tract (FGT) serves as a primary site of HIV acquisition, but gaps in knowledge remain regarding protective innate immune mechanisms. Innate lymphoid cells are tissue-resident cells involved in mucosal barrier maintenance and protection, and innate lymphoid cells (ILCs) are altered during chronic HIV infection.
