Activated Factor X signaling via protease-activated receptor 2 suppresses pro-inflammatory cytokine prodution from LPS-stimulated myeloid cells.
(2014)Vitamin K-dependent proteases generated in response to vascular injury and infection enable fibrin clot formation, but also trigger distinct immuno-regulatory signaling pathways on myeloid cells. Factor Xa, a protease ... -
Activation of human invariant natural killer T cells with a thioglycoside analogue of ?-galactosylceramide
(2011)Activation of CD1d-restricted invariant NKT (iNKT) cells with the glycolipid ?-galactosylceramide (?-GalCer) confers protection against disease in murine models, however, clinical trials in humans have had limited impact. ... -
Aging impairs peritoneal but not bone marrow-derived macrophage phagocytosis.
(2014)Aging results in deterioration of the immune system, which is associated with increased susceptibility to infection and impaired wound healing in the elderly. Phagocytosis is an essential process in both wound healing and ... -
The alarmin IL-33 promotes regulatory T-cell function in the intestine.
(2014)FOXP3(+) regulatory T cells (Treg cells) are abundant in the intestine, where they prevent dysregulated inflammatory responses to self and environmental stimuli. It is now appreciated that Treg cells acquire tissue-specific ... -
Bcl11b is essential for group 2 innate lymphoid cell development
(2015)Group 2 innate lymphoid cells (ILC2s) are often found associated with mucosal surfaces where they contribute to protective immunity, inappropriate allergic responses, and tissue repair. Although we know they develop from ... -
Blockade of B7-H1 (Programmed Death Ligand 1) Enhances Humoral Immunity by Positively Regulating the Generation of T Follicular Helper Cells
(2011)T follicular helper (TFH) cells are critical initiators in the development of T cell-dependent humoral immunity and the generation of protective immunity. We demonstrate that TFH cell accumulation and Ab production are ... -
Btk regulates macrophage polarization in response to lipopolysaccharide.
(2014)Bacterial Lipopolysaccharide (LPS) is a strong inducer of inflammation and does so by inducing polarization of macrophages to the classic inflammatory M1 population. Given the role of Btk as a critical signal transducer ... -
The C-type lectin SIGNR1 binds Schistosoma mansoni antigens in vitro, but SIGNR1-deficient mice have normal responses during schistosome infection
(American Society for Microbiology, 2009)The de novo immune response to infectious organisms arises from the innate recognition of pathogen-associated molecular patterns (PAMPs) by the host's pattern recognition receptors (PRRs). As the generation of type 2 ... -
Characterization of signaling pathways activated by the interleukin 1 (IL-1) receptor homologue T1/ST2. A role for Jun N-terminal kinase in IL-4 induction
(American Society for Biochemistry and Molecular Biology, 2002)T1/ST2 is a member of the interleukin (IL)-1 receptor superfamily, possessing three immunoglobulin domains extracellularly and a Toll/IL1R (TIR) domain intracellularly. The ligand for T1/ST2 is not known. T1/ST2 is expressed ... -
Cutting edge: IL-25 elicits innate lymphoid type 2 and type II NKT cells that regulate obesity in mice.
(2013)The cellular composition of visceral adipose tissue (VAT) and release of cytokines by such cells within VAT has been implicated in regulating obesity and metabolic homeostasis. We show the importance of IL-25-responsive ... -
Decoy receptors in the regulation of T Helper cell type 2 response
(The Rockefeller University Press, 2003) -
An enhanced in vivo stable isotope labeling by amino acids in cell culture (SILAC) model for quantification of drug metabolism enzymes.
(2015)Many of the enzymes involved in xenobiotic metabolism are maintained at a low basal level and are only synthesized in response to activation of upstream sensor/effector proteins. This induction can have implications in a ... -
Farnesoid X receptor agonists attenuate colonic epithelial secretory function and prevent experimental diarrhoea in vivo.
(2014)OBJECTIVE: Bile acids are important regulators of intestinal physiology, and the nuclear bile acid receptor, farnesoid X receptor (FXR), is emerging as a promising therapeutic target for several intestinal disorders. ... -
Filaggrin loss-of-function mutations are associated with enhanced expression of IL-1 cytokines in the stratum corneum of patients with atopic dermatitis and in a murine model of filaggrin deficiency.
(2012)Background Filaggrin (FLG) mutations result in reduced stratum corneum (SC) natural moisturizing factor (NMF) components and consequent increased SC pH. Because higher pH activates SC protease activity, we hypothesized ... -
Flotillin microdomains interact with the cortical cytoskeleton to control uropod formation and neutrophil recruitment
(2010)We studied the function of plasma membrane microdomains defined by the proteins flotillin 1 and flotillin 2 in uropod formation and neutrophil chemotaxis. Flotillins become concentrated in the uropod of neutrophils after ...
