SerpinB1 is an endogenous inhibitor of serine proteases recognized for its anti-inflammatory and host-protective properties. Although loss of serpinB1 in mice does not result in gross immune deregulation, serpinb1a(-/-) mice display increased mortality and inflammation-associated morbidity upon challenge with influenza virus. Here, we show that IL-17A(+) γδ and CD4(+) Th17 cells are already exp...
Mastitis, one of the most costly diseases in dairy ruminants, is an inflammation of the mammary gland caused by pathogenic infection. The mechanisms of adaptive immunity against pathogens in mastitis have not been fully elucidated. To investigate T helper cell-mediated adaptive immune responses, we established a mastitis model by challenge with an inoculum of 4 × 106 colony-forming units of Sta...
Transcription factor T-bet regulates inflammatory arthritis through its function in dendritic cells.
The transcription factor T-bet (Tbx21) plays a major role in adaptive immunity and is required for optimal IFN-gamma production by DCs. Here we demonstrate an essential function for T-bet in DCs in controlling inflammatory arthritis. We show that collagen antibody-induced arthritis (CAIA), a model of human RA, is a bipartite disease characterized by an early innate immune system component intac...
Genetic analyses identified Ses1 as a significant quantitative trait locus influencing the carrier state of 129S6 mice following a sublethal challenge with Salmonella enterica serovar Enteritidis. Previous studies have determined that Slc11a1 was an excellent candidate gene for Ses1. Kinetics of infection in 129S6 mice and Slc11a1-deficient (129S6-Slc11a1(tm1Mcg)) mice demonstrated that the wil...
immunohistochemistry for GATA3 on an independent series of cases, Wang et al also showed that GATA3 expression, evidenced in almost half of the cases, identifies a high-risk subset of PTCL, NOS. Although the findings in these 2 independent cohorts are convergent, it will be useful to confirm the clinical correlation of the GATA3 vs TBX21 profiles in another series of PTCL, NOS patients, if poss...
Immune checkpoint inhibitors blocking the interaction between programmed death-1 (PD-1) and PD-1 ligand-1 (PD-L1) are revolutionizing the cancer immunotherapies with durable clinical responses. Although high expression of PD-L1 in tumor tissues has been implicated to correlate with the better response to the anti-PD-1 therapies, this association has been controversial. In this study, to charact...
Cystic fibrosis (CF) is an autosomal recessive disease caused by mutations in the CF transmembrane conductance regulator (CFTR) gene. Mutations in this chloride channel lead to mucus accumulation, subsequent recurrent pulmonary infections, and inflammation, which, in turn, cause chronic lung disease and respiratory failure. Recently, rates of nontuberculous mycobacterial (NTM) infections in CF ...
PURPOSE The mechanisms involved in the appearance of a second neoplasia in patients with Hodgkin's disease (HD) are probably related to the genomic damage induced by the treatments administered and its repair. Here, we searched for some constitutive molecular mechanisms that in a basal manner may influence the behavior of HD patients. EXPERIMENTAL DESIGN We aimed to evaluate with the Comet As...
This study compared second-generation chimeric antigen receptors (CAR) encoding signaling domains composed of CD28, ICOS, and 4-1BB (TNFRSF9). Here, we report that certain CARs endow T cells with the ability to undergo long-term autonomous proliferation. Transduction of primary human T cells with lentiviral vectors encoding some of the CARs resulted in sustained proliferation for up to 3 months...
Posttranscriptional modification of histones by methylation plays an important role in regulating Ag-driven T-cell responses. We have recently drawn correlations between allogeneic T-cell responses and the histone methyltransferase Ezh2, which catalyzes histone H3 lysine 27 trimethylation. The functional relevance of Ezh2 in T-cell alloimmunity remains unclear. Here, we identify a central role ...
