ABSTRACT The placental intervillous space is a unique immunological niche where circulating maternal immune cells come into direct contact with the fetal syncytiotrophoblast. While adaptations in immune cell composition are known to occur in the maternal decidua throughout pregnancy, it remains unclear whether similar … Read more

ABSTRACT Immunological memory elicited either through previous or ongoing M. tuberculosis (Mtb) infection provides a critical mechanism by which hosts protect against re-infection and disease progression upon Mtb re-exposure. Conversely, the uneven competition between distinct Mtb strains suggest certain bacterial clades have enhanced ability … Read more

ABSTRACT Intravenous (IV) vaccination with Bacillus Calmette-Guerin (BCG) mediates sterilizing immunity against Mycobacterium tuberculosis (Mtb) in rhesus macaques but the cellular mechanisms underlying protection are undefined. We used mass cytometry (CyTOF) to broadly profile pulmonary immunity induced by IV BCG and observed an expansion … Read more

ABSTRACT Radiotherapy (RT) is essential in treating abdominal and pelvic cancers but often damages the healthy tissues, particularly the intestines, leading to radiation-induced toxicities with limited treatment options. While the immune system is known to help regulate tissue damage, immune mechanisms involved in RT-induced … Read more

ABSTRACT The immune balance in mucosal tissues depends on a delicate interplay between inflammatory T helper 17 (Th17) cells and immunosuppressive regulatory T cells (Tregs). But what happens when this balance is disturbed? In this study, we uncovered a critical role for acyl-CoA synthetase … Read more

ABSTRACT Xenobiotics and environmental factors implicated in inflammatory bowel disease (IBD) are metabolized by cytochrome P450 enzymes. Cyp2s1, an orphan member of this family, is highly expressed in the intestine, yet its role remains unclear. Here, we investigated the function of Cyp2s1 in intestinal … Read more

ABSTRACT T follicular helper cells (TFH) play a central role in orchestrating antibody mediated immunity. Despite the importance of antibody responses, especially allergen-specific IgE, in allergic airway diseases (AAD) such as asthma, the precise role TFH play in AADs has remained elusive. Using a … Read more

ABSTRACT Acute lung injury is a common complication of pneumonia, with disease severity linked to inflammatory cell recruitment and lung barrier dysfunction. In this study, we investigate the role of neutrophil-chemoattractant CXCL5 in lung barrier function and inflammation. We examined CXCL5 in patients with … Read more

ABSTRACT The upper airway is comprised of two distinct mucosal surface tissues, the respiratory mucosa (RM) and the olfactory mucosa (OM), both of which are constantly being exposed to airborne pathogens. The olfactory mucosa is responsible for detecting and conveying odorant information into the … Read more
