ABSTRACT Chronic gastrointestinal diseases are a significant global health burden that can require the use of gastrointestinal-cleansing regimens for diagnostics or therapeutic treatment. These regimens are beneficial for facilitating surgical preparation, drug delivery, colorectal cancer screenings, and personal use is common among proponents of … Read more

ABSTRACT As professional and long-lived immunoglobulin (Ig) producers, B cells represent attractive candidates for adoptive immunotherapy and their highly expressed Ig heavy (IgH) chain locus is ideal for editing. Each of its constant genes, expressed after class switch recombination (CSR), affords an attractive platform … Read more

ABSTRACT Intestinal fibrosis is one of the most threatening complications of Crohn’s disease (CD). Although our previous study identified the profibrotic role of amphiregulin (AREG) in intestinal fibrosis, the underlying molecular mechanisms remain poorly understood. This study aimed to elucidate the mechanisms by which … Read more

ABSTRACT A principal reason for the high global morbidity and mortality of tuberculosis (TB) is the lack of efficacy of the only licensed TB vaccine, Bacillus Calmette-Guérin (BCG), as intradermal BCG does not induce local pulmonary immune memory. Animal studies have shown that inhalation … Read more

ABSTRACT IL-17-producing lymphocytes are involved in both tissue repair and the propagation of inflammation, with their effects highly context-dependent. Mucosal-Associated-Invariant-T-cells (MAIT), a subset of innate-like T cells with features of both Th1 and Th17 lineages, are increasingly recognized for their roles in mucosal immunity. … Read more

ABSTRACT Inflammatory chemokine receptors CCR1/2/3/5 (iCCRs) play an important role in the recruitment of immune cells involved in innate immune functions and orchestrating the adaptive immune response. Here we utilise an influenza A virus (IAV) challenge to investigate the combinatorial roles of the iCCRs … Read more

ABSTRACT The REG/Reg gene locus encodes a conserved family of potent antimicrobial but also pancreatitis-associated proteins. Here we investigated whether REG/Reg family members differ in their baseline expression levels and abilities to be regulated in the pancreas and gut upon perturbations. We found, in … Read more

ABSTRACT Helminth infections affect billions of people worldwide and cause substantial morbidity. Intestinal helminth infection provokes Type 2 inflammation orchestrated by CD4+ T helper type 2 (Th2) cells. Th2 cells cooperate with group 2 innate lymphoid cells (ILC2s) to produce interleukin (IL)-4 and IL-13 … Read more

ABSTRACT The parasite Cryptosporidium is a leading cause of diarrhea and death in malnourished children and immunocompromised individuals and an important enteric pathogen of livestock. A mucosal vaccine to mitigate clinical disease and decrease transmission would address the public health impact of this organism, … Read more

ABSTRACT Staphylococcus aureus is a significant cause of pulmonary infections, but existing mouse models fail to recapitulate human-specific responses. In this study, we developed a novel mouse model of S. aureus infection using humanized mice implanted with autologous fetal lung tissue. We show that … Read more
