Center for Cell Engineering, Sloan Kettering Institute, New York, NY.
Purpose: We designed a CD19-targeted chimeric antigen receptor (CAR) comprising a calibrated signaling module, termed 1XX, that differs from that of conventional CD28/CD3ζ and 4-1BB/CD3ζ CARs. Preclinical data demonstrated that 1XX CARs generated potent effector function without undermining T-cell persistence. We hypothesized that 1XX CAR T cells may be effective at low doses and elicit minimal toxicities.

Purpose: Several studies suggest a linkage between PCOS and autoimmunity with a high frequency of chronic autoimmune thyroiditis (AIT) reported in PCOS patients, however, this subject remains controversial. The aim of this study was to investigate the prevalence of AIT in PCOS women and identify parameters that would serve as independent predictors of AIT.
Methods: Two hundred fifty seven (257) PCOS patients according to the NIH criteria and one hundred forty three (143) controls, women with normal menstrual cycles and without clinical or biochemical hyperandrogenism, were recruited for the study.
Elusive modes of Foxp3 activity in versatile regulatory T cells.

Department of Immunology, St. Jude Children's Research Hospital, Memphis, TN, United States.
Foxp3-expressing CD4 regulatory T (Treg) cells play a crucial role in suppressing autoimmunity, tolerating food antigens and commensal microbiota, and maintaining tissue integrity. These multifaceted functions are guided by environmental cues through interconnected signaling pathways. Traditionally, Treg fate and function were believed to be statically determined by the forkhead box protein Foxp3 that directly binds to DNA.

Background: Patients with chronic hepatitis B virus (HBV) infection are characterized by impaired immune response that fails to eliminate HBV. Immune checkpoint molecules (ICMs) control the amplitude of the activation and function of immune cells, which makes them the key regulators of immune response.
Methods: We performed a multiparametric flow cytometry analysis of ICMs and determined their expression on intrahepatic lymphocyte subsets in untreated and treated patients with HBV in comparison with non-pathological liver tissue.
The Performance of the American Thyroid Association (ATA) and American College of Radiology (ACR-TIRAD) Thyroid Nodule Risk-Stratification Systems in Determining High-Risk Nodules, and the Correlation of Site, Size, and Autoimmunity with High-Risk Features.

Introduction: Neck ultrasonography (US) and fine-needle aspiration (FNA) biopsy are usually used to evaluate thyroid nodules. This study aimed to evaluate the performance of two popular thyroid imaging reporting systems in detecting thyroid malignancy and to evaluate the correlation between thyroid autoimmunity, nodule site, and size in the development of malignancy.
Methods: This prospective study was conducted from January 2019 to July 2021 in Basrah, Iraq.
