Parse Biosciences and Nomic Announce 100 Million Cell, Multimodal AI-ready Dataset for Immune Biology

[Parse Biosciences] Parse Biosciences and Nomic Bio announced their partnership to generate Cascade, a 100 Million cell foundational dataset to understand the human immune response.

Forlong Biotechnology Announces First Patient Dosed in Phase I Clinical Trial of Subcutaneous FL115 (IL-15 Superagonist) in Australia

[Forlong Biotechnology] Forlong Biotechnology announced that the first patient has been dosed in a Phase I study of subcutaneous FL115, an engineered IL-15/IL-15Rα-Fbody® fusion protein designed to stimulate NK cells and T cells, in patients with advanced solid tumors in Australia.

Persistent and Compartmentalized T Cell Immunity in ALS

[Nature Medicine] Investigators used single-cell RNA and T cell receptor sequencing, longitudinal immune profiling, and imaging flow cytometry to identify long-lived intrathecal clonotypes and antigen-presenting cell–T cell complexes displaying features of immunological synapse formation, consistent with intrathecal antigen presentation.

Tandem Repeat Variation Shapes Immune Cell Type-Specific Gene Expression

[Nature] Scientists generated whole-genome and single-cell RNA sequencing from more than 5.4 million blood-derived cells across 1,925 individuals in two cohorts, and perform meta-analysis to characterize the impact of variation in more than 1.7 million tandem repeats loci on immune cell type-specific gene expression.

T and B Cells Recognize Splicing-Derived Neutrophil Neoantigens in Lupus

[Nature] The authors reported that neutrophils from patients with systemic lupus erythematosus, unlike neutrophils from healthy donors or patients with rheumatoid arthritis, contain many aberrantly spliced gene transcripts.

Autoimmune-Shared Immune States Converge in a CXCL12-CXCR4 Fibroblast-Immune Niche in Chronic Antibody-Mediated Rejection

[Signal Transduction and Targeted Therapy] Scientists integrated single-cell profiles from peripheral blood and kidney graft samples from patients with chronic antibody-mediated rejection or stable allograft function and healthy controls, bulk transcriptomic datasets, spectral flow cytometry, multiplex immunofluorescence, high-resolution spatial transcriptomics, and a large blood immune reference spanning autoimmune and inflammatory diseases.

Pancreatic δ Cells Are Resistant to Auto- and Paracrine Inhibition in Human Type-2 Diabetes

[Proceedings of The National Academy of Sciences of The United States of America] Researchers compared the function of isolated pancreatic δ cells of cadaveric nondiabetic and T2D donors by single cell total internal reflection microscopy, electrophysiology, and secretion measurements.

Cysteine Promotes Islet α-Cell Glucagon Secretion by Limiting Oxidative Inhibition of Voltage-Gated Sodium Channels

[Redox Biology] Scientists identified cysteine as a key regulator of islet glucagon secretion through redox control of α-cell electrical excitability.

Imeglimin at Clinical Doses Promotes Glucose-Stimulated Insulin Secretion and Mitochondrial Supercomplex Formation

[Endocrinology] Investigators examined the effects of imeglimin, a novel antidiabetic agent, in normal glucose-tolerant C57BL/6 mice and isolated mouse islets using concentrations corresponding to clinically achieved plasma levels.
