Abstract Purpose: BRAF mutations are divided into functional classes distinguished by signaling mechanism and kinase activity: V600-mutant kinase-activating monomers (class I), dimers II), kinase-inactivating heterodimers III). The relationship between class disease characteristics in BRAF-mutant non–small cell lung cancer (NSCLC) has not been fully explored. Experimental Design: We performed a retrospective analysis of NSCLCs treated at 2 institutions from 2005 to 2017 determine...
The pleiotropic actions of interleukin-2 (IL-2) are essential for regulation immune responses and maintenance tolerance. IL-2 receptor (IL-2R) is composed IL-2Rα, IL-2Rβ, IL-2Rγ subunits, with defects in IL-2Rα their downstream signaling effectors resulting known primary immunodeficiency disorders. Here, we report the first human defect occurring two infant siblings a homozygous IL2RB mutation WSXWS motif, manifesting as multisystem autoimmunity susceptibility to CMV infection. hypomorphic...

Despite the therapeutic efficacy of immune checkpoint inhibitors (ICIs) in a subset patients, consistent and easily obtainable predictors remain elusive.
Implementing cancer precision medicine in the clinic requires assessing therapeutic relevance of genomic alterations. A main challenge is systematic interpretation whole-exome sequencing (WES) data for clinical care.One hundred sixty-five adults with metastatic colorectal and lung adenocarcinomas were prospectively enrolled CanSeq study. WES was performed on DNA extracted from formalin-fixed paraffin-embedded tumor biopsy samples matched blood samples. Somatic germ-line alterations ranked...
Metabolic imbalance leading to inflammatory hypoxia and stabilization of hypoxia-inducible transcription factors (HIFs) is a hallmark bowel diseases. We hypothesize that HIF could be stabilized in CD4+ T cells during intestinal inflammation alter the functional responses via regulation microRNAs. Our assays reveal markedly increased cell-intrinsic protein experimental colitis. microRNA screen primary points us towards miR-29a our subsequent studies identify selective role for HIF-2α...
The chemokines are a large family of mainly secreted molecules involved in the regulation numerous physiological and pathophysiological processes. Despite many years investigation, precise cellular sources most have remained incompletely defined as consequence limited availability suitable reagents to visualize expression chemokine proteins at single-cell level. Here, we developed simple flow cytometry–based assay using commercially available chemokine-specific antibodies for efficient...
The choreography of complex immune responses, including the priming, differentiation, and modulation specific effector T cell populations generated in immediate wake an acute pathogen challenge, is part controlled by chemokines, a large family mostly secreted molecules involved chemotaxis other patho/physiological processes. cells are both responsive to various chemokine cues relevant source for certain chemokines themselves; yet, actual range, regulation, role cell-derived remains...
Despite the prevalence of Aspergillus-related disease in immune suppressed lung transplant patients, little is known host-pathogen interaction. Because mould's angiotropic nature and because its capacity to thrive hypoxic conditions, we hypothesized that degree Aspergillus invasion would increase with progressive rejection-mediated ischemia allograft. To study this relationship, utilized a novel orthotopic tracheal model infection, which it was possible assess effects tissue hypoxia on...
Inflammatory bowel disease [IBD] is characterised by a disruption of immune homeostasis, which tightly regulated to protect against harmful pathogens yet not react commensal antigens. Animal studies indicate that regulatory T cells [Treg] modulate the response prevent IBD development. Lactoferrin [LF] an endogenous anti-inflammatory pleiotropic protein secreted at high concentrations in colostrum and mucosal sites. However, effect LF on specific lymphocyte populations has been studied. Here,...
Abstract The clinical significance of gene fusions detected by DNA-based next generation sequencing remains unclear as resistance mechanisms to EGFR tyrosine kinase inhibitors in mutant non-small cell lung cancer. By studying inhibitor-resistant patients treated with a combination an inhibitor and drug targeting the putative resistance-causing fusion oncogene, we identify who benefit those do not from this treatment approach.
