One Of The Biggest Impact Things You Can Do To Live Longer.

Dr. Paddy Barrett

“But what can I do to make a difference?” This is one of the most common questions I get as a cardiologist when talking about preventing heart disease and living longer. As a doctor, there are many things I can do, and only a doctor can do: Prescribe medications Order certain diagnostic tests. Perform or arrange medical procedures. And so on.

Targeting aryl hydrocarbon receptor functionally restores tolerogenic dendritic cells derived from patients with multiple sclerosis

Journal of Clinical Investigation - Cardiology

Multiple sclerosis (MS) is a chronic disease characterized by dysregulated self-reactive immune responses that damage the neurons’ myelin sheath, leading to progressive disability. The primary therapeutic option, immunosuppressants, inhibits pathogenic anti-myelin responses but depresses the immune system. Antigen-specific monocyte-derived autologous tolerogenic dendritic cells (tolDCs) offer alternative therapeutic approaches to restore tolerance to autoantigens without causing generalized immu

Targeting TET3 in macrophages provides a concept strategy for the treatment of endometriosis

Journal of Clinical Investigation - Cardiology

Endometriosis, characterized by the presence of endometrial-like tissue outside the uterus, is a condition associated with pain and infertility. In this issue of the JCI, Lv et al. illuminate the critical pathophysiological role of the ten-eleven translocation 3 (TET3) in endometriosis. TET3 expression levels were higher in macrophages of endometriotic lesions compared with control endometrial tissue, implicating TET3 as a contributing factor in the chronic inflammation that occurs in endometrio

West Nile virus triggers intestinal dysmotility via T cell–mediated enteric nervous system injury

Journal of Clinical Investigation - Cardiology

Intestinal dysmotility syndromes have been epidemiologically associated with several antecedent bacterial and viral infections. To model this phenotype, we previously infected mice with the neurotropic flavivirus West Nile virus (WNV) and demonstrated intestinal transit defects. Here, we found that within 1 week of WNV infection, enteric neurons and glia became damaged, resulting in sustained reductions of neuronal cells and their networks of connecting fibers.

More T cell receptors to the RAScue in cancer?

Journal of Clinical Investigation - Cardiology

Treatment with T cells genetically engineered to express tumor-reactive T cell receptors (TCRs), known as TCR-gene therapy (TCR-T), is a promising immunotherapeutic approach for patients with cancer. The identification of optimal TCRs to use and tumor antigens to target are key considerations for TCR-T. In this issue of the JCI, Bear and colleagues report on their use of in vitro assays to characterize four HLA-A*03:01– or HLA-A*11:01–restricted TCRs targeting the oncogenic KRAS G12V mutation.

IL-13 induces loss of CFTR in ionocytes and reduces airway epithelial fluid absorption

Journal of Clinical Investigation - Cardiology

The airway surface liquid (ASL) plays a crucial role in lung defense mechanisms, and its composition and volume are regulated by the airway epithelium. The cystic fibrosis transmembrane conductance regulator (CFTR) is abundantly expressed in a rare airway epithelial cell type called an ionocyte. Recently, we demonstrated that ionocytes can increase liquid absorption through apical CFTR and basolateral barttin/chloride channels, while airway secretory cells mediate liquid secretion through apical

Epigenetic regulation of cell state by H2AFY governs immunogenicity in high-risk neuroblastoma

Journal of Clinical Investigation - Cardiology

Childhood neuroblastoma with MYCN amplification is classified as high risk and often relapses after intensive treatments. Immune checkpoint blockade therapy against the PD-1/L1 axis shows limited efficacy in patients with neuroblastoma, and the cancer intrinsic immune regulatory network is poorly understood. Here, we leverage genome-wide CRISPR/Cas9 screens and identify H2AFY as a resistance gene to the clinically approved PD-1 blocking antibody nivolumab.

Respiratory syncytial virus (RSV) selectively targets ciliated cells in human bronchial epithelium and can cause bronchiolitis and pneumonia, mostly in infants. To identify molecular targets of intervention during RSV infection in infants, we investigated how age regulates RSV interaction with the bronchial epithelium barrier. Employing precision-cut lung slices and air-liquid interface cultures generated from infant and adult human donors, we found robust RSV virus spread and extensive apoptoti
