The phenotype of infused cells is a major determinant of Adoptive T-cell therapy (ACT) efficacy. Yet, the difficulty in deciphering multiparametric cytometry data limited the fine characterization of cellular products. To allow the analysis of dynamic and complex flow cytometry samples, we developed cytoChain, a novel dataset mining tool and a new analytical workflow. CytoChain was challenged to compare state-of-the-art and innovative culture conditions to generate stem-like memory cells (TSCM) suitable for ACT. Noticeably, the combination of IL-7/15 and superoxides scavenging sustained the emergence of a previously unidentified nonexhausted Fit-TSCM signature, overlooked by manual gating and endowed with superior expansion potential. CytoChain proficiently traced back this population in independent datasets, and in T-cell receptor engineered lymphocytes. CytoChain flexibility and function were then further validated on a published dataset from circulating T cells in COVID-19 patients. Collectively, our results support the use of cytoChain to identify novel, functionally critical immunophenotypes for ACT and patients immunomonitoring. 相似文献

In a recent issue of The Journal of Pathology, Iampietro et al isolated and characterized several clones of urine‐derived podocytes from three patients with Alport syndrome (AS) and proteinuria and one age‐matched non‐proteinuric control. They reported differential expression of genes involved in cell motility, adhesion, survival, and angiogenesis. The authors found AS podocytes to be less motile and to have significantly higher permeability to albumin compared to control podocytes, highlighting that AS podocytes may retain their phenotype even when losing contact with the glomerular basement membrane. The establishment of urine‐derived podocyte cell lines from patients with different genetic forms of AS may represent a valuable and minimally invasive tool to investigate the cellular mechanisms contributing to kidney disease progression in AS and may allow for the establishment of patient‐specific drug screening opportunities. © 2020 The Pathological Society of Great Britain and Ireland.

Permissive beliefs relate to the acceptability of engaging in alcohol use in spite of obvious potential negative consequences. They are considered the most proximal and precipitating cognitive factor in the decision to use alcohol and/or the activation of strategies to obtain it. Recent research suggested that ‘desire thinking’ may be involved in the escalation of craving and addictive behaviours and can play a role in strengthening permissive beliefs. The current study tested whether the induction of desire thinking would have a stronger effect on rate of conviction in permissive beliefs compared to a control cognitive response in the form of neutral thinking and whether this effect would be specific for patients with alcohol use disorder (AUD). Thirty AUD patients and 30 social drinkers (SD) were randomly allocated to two thinking manipulation tasks (desire thinking and neutral thinking). Current permissive beliefs were measured before and after manipulation and after a resting phase. Findings showed that desire thinking increased the level of current permissive beliefs after manipulation relative to the neutral thinking condition for the AUD group but not for the SD group. This effect was not purely dependent on the concurrent level of perceived craving. This study supports a causal relationship between the induction of desire thinking and rate of conviction in permissive beliefs and highlights the relevance of targeting desire thinking in the treatment for AUD patients. 相似文献

We describe a case of ruptured aneurysm of the right coronary sinus of Valsalva (ASV) diagnosed by transthoracic two-dimensional echocardiography which allowed to quickly establish a correct diagnosis in a patient with a recent onset of continuous murmur and acute right congestive heart failure. 相似文献

Two new natural CphA metallo-β-lactamases, the CphA4 and CphA5 enzymes, were identified in water samples from municipal sewage in central Italy. Compared to CphA, the CphA4 and CphA5 enzymes showed numerous point mutations. These enzymes have a narrow spectrum of substrates focused on carbapenems only. CphA5 showed kcat values about 40-, 12-, and 97-fold higher than those observed for CphA4 versus imipenem, ertapenem, and biapenem, respectively. 相似文献
