Dawn of CAR-T cell therapy in autoimmune diseases

Chimeric antigen receptor(CAR)-T cell therapy has achieved remarkable success in the treatment of hematological malignancies.Based on the immunomodulatory capability of CAR-T cells,efforts have turned toward exploring their potential in treating autoimmune diseases.Bibliometric analysis of 210 records from 128 academic journals published by 372 institutions in 40 countries/regions indicates a growing number of publications on CAR-T therapy for autoimmune diseases,covering a range of subtypes such as systemic lupus erythematosus,multiple sclerosis,among others.CAR-T therapy holds promise in mitigating several shortcomings,including the indiscriminate suppression of the immune system by traditional immunosuppressants,and non-sustaining therapeutic levels of monoclonal antibodies due to inherent pharmacokinetic constraints.By persisting and proliferating in vivo,CAR-T cells can offer a tailored and precise therapeutics.This paper reviewed preclinical experiments and clinical trials involving CAR-T and CAR-related therapies in various autoimmune diseases,incorporating innovations well-studied in the field of hematological tumors,aiming to explore a safe and effective therapeutic option for relapsed/refractory autoimmune diseases.

Early stage of radiological expertise modulates resting-state local coherence in the inferior temporal lobe

Background The visual system and its inherent functions undergo experience-dependent changes through the lifespan,enabling acquisition of new skills.Previous fMRI studies using tasks reported increased specialization in a number of cortical regions subserving visual expertise.Although ample studies focused on representation of long-term visual expertise in the brain,i.e.in terms of year,monthly-based early-stage representation of visual expertise remains unstudied.Given that spontaneous neuronal oscillations actively encode previous experience,we propose brain representations in the resting state is fundamentally important.Objective The current study aimed to investigate how monthly-based early-stage visual expertise are represented in the resting state using the expertise model of radiologists.Methods In particular,we investigated the altered local clustering pattern of spontaneous brain activity using regional homogeneity(ReHo).A cohort group of radiology interns(n=22)after one-month training in X-ray department and matched laypersons(n=22)were recruited after rigorous behavioral assessment.Results The results showed higher ReHo in the right hippocampus(HIP)and the right ventral anterior temporal lobe(vATL)(corrected by Alphasim correction,P<0.05).Moreover,ReHo in the right HIP correlated with the number of cases reviewed during intern radiologists’training(corrected by Alphasim correction,P<0.05).Conclusions In sum,our results demonstrated that the early stage of visual expertise is more concerned with stabilizing visual feature and domain-specific knowledge into long-term memory.The results provided novel evidence regarding how early-stage visual expertise is represented in the resting brain,which help further elaborate how human visual expertise is acquired.We propose that our current study may provide novel ideas for developing new training protocols in medical schools.
