Highly Active CAR T Cells that Bind to a Juxta-Membrane Region of Mesothelin and are Not Blocked by Shed Mesothelin

ABSTRACT: Identification of the major protease sites in MSLN and preparation of a monoclonal antibody, 15B6, that binds next to cell membrane at the protease sensitive region and inhibits MSLN shedding. Mab 15B6 makes very active CAR-T cells whose activity is not blocked by shed MSLN. The 15B6 CAR-T cells have greatly superior anti-tumor activity in mice than CAR-T cells targeting an epitope in shed MSLN.

Quantitative proteomic analysis of human malignant ascites

Project description:Ascites is a valuable source of cancer biomarkers, because it contains a variety of secreted and shed proteins from cancerous cells. Conversely, most proteomic studies on ascites have focused on ovarian cancer and provided insufficient depth for biomarker discovery. Further, no proteomic analysis of ascites from gastric cancer has been reported. To this end, we profiled the human ascites proteome to obtain a pool of biomarker candidates using comprehensive proteomic strategies. Subsequently, label-free quantitation was performed to compare the abundance of proteins between benign disease and gastric cancer patients.

stem cells from human exfoliated deciduous teeth cultured with human platelet lysate

Project description:Stem cells from human exfoliated deciduous teeth (SHED) can be used as a potential clinical material. But the use of xenogeneic ingredients, especially fetal bovine serum, will increase the risk of zoonotic disease transmission during the use of animal-derived products. Human-platelet-lysate (hPL) was used in human cell expansion with reliability in clinical applications. This study aimed to explore the feasibility and effect of HPL in the cultivation of SHED. We use proteomics to interpret the impact of HPL on the protein profile of SHED. Propagation, differentiation, qPCR and immunofluorescence were used to detect the effect of HPL on SHED.

Transcriptomic profiling of shed cells enables spatial mapping of cellular turnover in human organs

Project description:Single-cell atlases provide valuable insights into gene expression states but lack information on cellular dynamics. Understanding cell turnover rates—the time between a cell’s birth and death—can shed light on stemness potential and susceptibility to damage. However, measuring turnover rates in human organs has been a significant challenge. In this study, we integrate transcriptomic data from both tissue and shed cells to assign turnover scores to individual cells, leveraging their expression profiles in spatially resolved expression atlases. By performing RNA sequencing on shed cells from the upper gastrointestinal tract, collected via nasogastric tubes, we infer turnover rates in the human esophagus, stomach, and small intestine. Additionally, we analyze colonic fecal washes to map turnover potential in the human large intestine. Our findings reveal a subset of short-lived, interferon-stimulated colonocytes within a distinct pro-inflammatory microenvironment. Our approach introduces a dynamic dimension to single-cell atlases, offering broad applicability across different organs and diseases.
