Engineering chimeric autoantibody receptor T cells for targeted B cell depletion in multiple sclerosis model: An study.

Background: Recent evidence suggests that B cells and autoantibodies have a substantial role in the pathogenesis of Multiple sclerosis. T cells could be engineered to express chimeric autoantibody receptors (CAARs), which have an epitope of autoantigens in their extracellular domain acting as bait for trapping autoreactive B cells. This study aims to assess the function of designed CAAR T cells against B cell clones reactive to the myelin basic protein (MBP) autoantigen.

Fat1 cadherin provides a novel minimal residual disease marker in acute lymphoblastic leukemia.

Measurement of minimal residual disease (MRD) maintains an important role in the clinical management of acute lymphoblastic leukemia (ALL). Recently, we identified Fat1 cadherin as a unique and independent prognostic factor for relapse-free and overall survival in pediatric pre-B-ALL. Here, we analyzed Fat1 mRNA for its potential as a novel marker of MRD in cases of pre-B- and T-ALL.

Effects of neuropeptide substance P on the expression of adhesion molecules in cord blood hematopoietic stem cells.

Modulation of adhesion molecules expression on the surface of cord blood (CB) CD34(+) cells may assist in overcoming the delay in cord blood engraftment. Likewise, utilization of diverse growth factors such as neuropeptides could also be helpful. Therefore, we aimed to assess the role of Substance P (SP) along with a cytokine cocktail on CB CD34(+) adhesion molecule expression.

Substance P and calcitonin gene-related neuropeptides as novel growth factors for ex vivo expansion of cord blood CD34(+) hematopoietic stem cells.

There is little evidence on roles of growth factors other than cytokines in expansion of cord blood (CB) stem cells. We aimed to explore a novel approach for expansion, using Substance P (SP) and calcitonin gene-related peptide (CGRP) neuropeptides. CB CD34(+) cells were cultured in different concentrations of SP and/or CGRP in combination with a cytokine cocktail.
