Identification of antigen-presenting cell-T cell interactions driving immune responses to food.

The intestinal immune system must concomitantly tolerate food and commensals and protect against pathogens. Antigen-presenting cells (APCs) orchestrate these immune responses by presenting luminal antigens to CD4 T cells and inducing their differentiation into regulatory (pTreg) or inflammatory (Th) subsets. We used a proximity labeling method (LIPSTIC) to identify APCs that presented dietary antigens under tolerizing and inflammatory conditions and understand cellular mechanisms by which tolerance to food is induced and can be disrupted by infection.

Phase I study of allogeneic monocyte-derived inflammatory dendritic cells in combination with pembrolizumab.

PD-1 checkpoint inhibition has revolutionized the care of cancer. A small portion of patients with stage IV cancer achieve durable control. But, early progression is common and dramatic control is achieved for only a minority.

Stimulating Soluble Guanylyl Cyclase with the Clinical Agonist Riociguat Restrains the Development and Progression of Castration-Resistant Prostate Cancer.

Castration-resistant prostate cancer (CRPC) is incurable and fatal, making prostate cancer the second-leading cancer-related cause of death for American men. CRPC results from therapeutic resistance to standard-of-care androgen deprivation (AD) treatments, through incompletely understood molecular mechanisms, and lacks durable therapeutic options. Here, we identified enhanced soluble guanylyl cyclase (sGC) signaling as a mechanism that restrains CRPC initiation and growth.

Large-scale analysis of CDH1 mutations defines a distinctive molecular subset with treatment implications in gastric cancer.

Although histological and molecular classifications have been extensively studied for gastric cancer (GC), targeted therapies for GC remain limited. CDH1 mutations (MT) are characteristic of genomically stable GC and are associated with poor prognosis, but lack effective or targeted therapies. Here, we showed the overall mutation frequency of CDH1 was 9.

Stability study of Nepeta cataria iridoids analyzed by LC/MS.

Introduction: Catnip (Nepeta cataria, L.) has well-documented applications in arthropod repellency because of its bioactive iridoids. Long-term stability of nepetalactones and other iridoids in N.
