A rapidly growing number of chimeric antigen receptors (CARs) is being translated into cell therapy for malignant and autoimmune diseases. While cancer cell-selective CAR targeting is undergoing continuous refinement, specific testing for overlooked recognition of healthy tissues is commonly not performed, which potentially results in underestimating of the risk of severe tissue damage upon CAR T cell application. Using the FcμR/IgM receptor/FAIM3/TOSO-specific CAR, designed to target chronic lymphocytic leukemia cells, we exemplarily outline a screen to uncover reactivities to healthy tissues and discuss the value of such pre-clinical testing to improve safety in CAR T cell application.

Background: Intervertebral disc degeneration (IVDD) is one of the main causes of chronic low back pain. The degenerative process is often initiated by an imbalance between catabolic and anabolic pathways. Despite the large socio-economic impact, the initiation and progress of disc degeneration are poorly understood.

This study aims to explore the relationship between the gut microbiome, serum metabolome, and FR in chronic LBP patients.
Methods: Serum metabolomic profiling and gut microbiome analysis were conducted in chronic LBP patients with and without FR (LBP + FR, = 40; LBP, = 40) and Healthy Controls (HC, = 31).
Objectives The optimal dosing schedule strategy for granulocyte colony-stimulating factor (G-CSF) in healthy stem cell donors remains controversial. This study aimed to compare the efficacy of once-daily versus twice-daily G-CSF administration in allogeneic stem cell donors. Materials and methods We retrospectively analyzed data from 388 healthy unrelated donors (282 males, 106 females) who underwent stem cell mobilization at our center between September 2018 and June 2022.

Dairy cows with clinical ketosis (CK) exhibit metabolic changes, including intense adipose tissue (AT) lipolysis and systemic insulin resistance, that increase plasma BHB and free fatty acids (FFA). Cows with CK also have systemic inflammation, predisposing them to inflammatory and infectious diseases. This inflammatory process is modulated in part by oxidized fatty acids (oxylipins) that regulate all aspects of inflammation.
