Multimodal Profiling of Peripheral Blood Identifies Proliferating Circulating Effector CD4 T Cells as Predictors for Response to Integrin α4β7-Blocking Therapy in Inflammatory Bowel Disease.

Background & Aims: Despite the success of biological therapies in treating inflammatory bowel disease, managing patients remains challenging due to the absence of reliable predictors of therapy response.

Methods: In this study, we prospectively sampled 2 cohorts of patients with inflammatory bowel disease receiving the anti-integrin α4β7 antibody vedolizumab. Samples were subjected to mass cytometry; single-cell RNA sequencing; single-cell B and T cell receptor sequencing (BCR/TCR-seq); serum proteomics; and multiparametric flow cytometry to comprehensively assess vedolizumab-induced immunologic changes in the peripheral blood and their potential associations with treatment response.

Soft-metal(loid)s induce protein aggregation in .

Metal(loid) salts were used to treat infectious diseases in the past due to their exceptional biocidal properties at low concentrations. However, the mechanism of their toxicity has yet to be fully elucidated. The production of reactive oxygen species (ROS) has been linked to the toxicity of soft metal(loid)s such as Ag(I), Au(III), As(III), Cd(II), Hg(II), and Te(IV).

[Pathological gambling, personality patterns and clinical syndromes].

The aim of this study is to evaluate the prevalence and percentages of personality patterns, and explore their relationship with clinical syndromes in a sample of 212 pathological gamblers from a rehabilitation center. The study also explores the possibility of profiles, common in gamblers, in which personality disorders and clinical syndromes coexist. The Millon Clinical Multiaxial Inventory (MCMIII) was employed.

Expression of progranulin (Acrogranin/PCDGF/Granulin-Epithelin Precursor) in benign and malignant ovarian tumors and activation of MAPK signaling in ovarian cancer cell line.

It has been recently demonstrated that progranulin is overexpressed in ovarian cancer and that this protein is involved in the stimulation of cell proliferation, malignancy, and chemoresistance in ovarian cancer. The goal of the present study was to establish the differences in progranulin expression among normal, benign, and malignant ovarian tissues and to identify the signal transduction pathways activated by progranulin in an ovarian cancer cell line. Compared with benign tumors and normal ovarian tissue, progranulin mRNA and protein were overexpressed in malignant tumors.
