Objectives: We focused on how the immunophenotypes based on the distribution of CD8-positive tumor-infiltrating lymphocytes (TILs) relate to the endometrial cancer (EC) molecular subtypes and patients' prognosis.
Patients And Methods: Two cohorts of EC patients (total n = 145) were analyzed and categorized using the Molecular Risk Classifier for Endometrial cancer (ProMisE): POLEmut (POLE mutation), MMRd (mismatch repair deficiency), NSMP (no specific molecular profile), and p53abn (p53 abnormality). CD8-positive TILs, within the central tumor and the invasive margin, were examined by using immunohistochemical staining and advanced image-analysis software.

Introduction: T cell Antigen Coupler (TAC) T cells harness all signaling subunits of endogenous T cell receptor (TCR) to trigger T-cell activation and tumor cell lysis, with minimal release of cytokines. Some of the major obstacles to cellular immunotherapy in solid tumors include inefficient cell infiltration into tumors, lack of prolonged cellular persistence, and therapy-associated toxicity.
Methods: To boost the cytotoxic potential of TAC-T cells against solid tumors, we generated a novel NECTIN-4-targeted TAC-T variant, NECTIN-4 TAC28-T, which integrated the co-stimulatory CD28 cytoplasmic region, and compared the anti-tumor activities between NECTIN-4 TAC-T cells and NECTIN-4 TAC28-T cells in vitro and vivo.

Background: Mucopolysaccharidosis (MPS) type 1 S and type 2 are rare lysosomal storage disorders characterized by impaired enzyme production, resulting in glycosaminoglycans accumulation within lysosomes. Enzyme Replacement Therapy (ERT) with laronidase and idursulfase are first line treatments, respectively. However, infusion-related hypersensitivity reactions (HR) may lead to ERT discontinuation.

A systematic review and meta-analysis were performed to evaluate the virus-specific T-cell response after COVID-19 mRNA vaccination, using the QuantiFERON SARS-CoV-2 interferon-γ release assay. A search was conducted (June 8, 2023) in the PUBMED, SCOPUS, and medRxiv databases, to identify studies reporting the QuantiFERON SARS-CoV-2 (Starter (two antigen tubes) or Starter + Extended Pack (three antigen tubes), cut-off ≥ 0.15 IU/mL) positivity rate (PR) in immunocompetent adults, following the administration of two or three COVID-19 mRNA vaccine doses.
