Therapeutic Effect of Anti-CD52 Monoclonal Antibody in Multiple Sclerosis and Its Animal Models Is Mediated via T Regulatory Cells.

J Immunol 2022 Jun 24. Epub 2022 Jun 24.

Department of Neurology, The University of North Carolina at Chapel Hill, Chapel Hill, NC;

The objective of this study is to determine the mechanism of action of anti-CD52 mAb treatment in patients with relapsing-remitting multiple sclerosis (RRMS). Experimental autoimmune encephalomyelitis (EAE), an animal model of the disease, was used to address the role of T regulatory cells (Tregs) in the anti-CD52 mAb-induced suppression of the disease. In vitro studies on PBMCs from RRMS patients and matched healthy controls determined the effect of IL-7 on the expansion of CD4CD25CD127 Tregs and induction of their suppressive phenotype. Read More

Translational regulation of TFH cell differentiation and autoimmune pathogenesis.

Sci Adv 2022 Jun 24;8(25):eabo1782. Epub 2022 Jun 24.

Department of Microbiology, New York University School of Medicine, New York, NY 10016, USA.

Little is known regarding T cell translational regulation. We demonstrate that T follicular helper (TFH) cells use a previously unknown mechanism of selective messenger RNA (mRNA) translation for their differentiation, role in B cell maturation, and in autoimmune pathogenesis. We show that TFH cells have much higher levels of translation factor eIF4E than non-TFH CD4 T cells, which is essential for translation of TFH cell fate-specification mRNAs. Read More

Retromer dysfunction in amyotrophic lateral sclerosis.

Proc Natl Acad Sci U S A 2022 Jun 24;119(26):e2118755119. Epub 2022 Jun 24.

Department of Pathology and Cell Biology, Columbia University Irving Medical Center, New York, NY 10032.

Retromer is a heteropentameric complex that plays a specialized role in endosomal protein sorting and trafficking. Here, we report a reduction in the retromer proteins-vacuolar protein sorting 35 (VPS35), VPS26A, and VPS29-in patients with amyotrophic lateral sclerosis (ALS) and in the ALS model provided by transgenic (Tg) mice expressing the mutant superoxide dismutase-1 G93A. These changes are accompanied by a reduction of levels of the α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptor subunit GluA1, a proxy of retromer function, in spinal cords from Tg SOD1 mice.

Adoption of Single-Use Clean Intermittent Catheterization Policies Do Not Appear to Effect Genitourinary Outcomes in a Large Spinal Cord Injury Cohort.

J Urol 2022 Jun 24:101097JU0000000000002836. Epub 2022 Jun 24.

Santa Clara Valley Medical Center, Department of Physical Medicine and Rehabilitation.

Introduction: In April 2008, Medicare amended their policy for clean intermittent catheter (CIC), increasing coverage from 4 re-used catheters per month to up to 200 single-use catheters. The primary reason for the policy change was an assumed decrease in risk of urinary tract infection (UTI) with single-use catheters. Given its economic/environmental impact (∼50-fold increase in cost and plastic waste) and a paucity of supporting evidence, we retrospectively evaluate the policies'effect in a prospective spinal cord injury (SCI) registry.
