IL-15 mediated expansion of rare durable memory T cells following adoptive cellular therapy.

J Immunother Cancer 2021 May;9(5)

Fred Hutchinson Cancer Research Center, Clinical Research Division, Seattle, WA, USA

Background: Synovial sarcoma (SS) and myxoid/round cell liposarcoma (MRCL) are ideal solid tumors for the development of adoptive cellular therapy (ACT) targeting NY-ESO-1, as a high frequency of tumors homogeneously express this cancer-testes antigen. Data from early phase clinical trials have shown antitumor activity after the adoptive transfer of NY-ESO-1-specific T cells. In these studies, persistence of NY-ESO-1 specific T cells is highly correlated with response to ACT, but patients often continue to have detectable transferred cells in their peripheral blood following progression.

The times they are a-changing - A refined proposal for finite HBV nucleos(t)ide analog therapy.

J Hepatol 2021 May 3. Epub 2021 May 3.

Foundation IRCCS Ca' Granda Ospedale Maggiore Policlinico, Division of Gastroenterology and Hepatology, Milan, Italy; CRC "A. M. and A. Migliavacca" Center for Liver Disease, Department of Pathophysiology and Transplantation, University of Milan, Milan, Italy.

Although discontinuation of nucleos(t)ide analogue (NA) treatment before HBsAg loss is part of all current hepatitis B virus (HBV) treatment guidelines for HBeAg-positive patients who achieved HBeAg seroconversion, a treatment endpoint known to be associated with silencing of HBV transcriptional activity and restoration of HBV-specific immune control, it is still highly controversial whether it is even appropriate to consider NA discontinuation before HBsAg loss in the HBeAg-negative phase. Despite the growing evidence that a relevant, albeit small, proportion of patients with HBeAg-negative disease can be cured by stopping NA treatment, the fear of discontinuation-associated relapse and the uncertainty of how to predict off-therapy response and monitor patients after discontinuation have generated scepticism and subsequently led to low implementation of this concept in the clinic. In this article, we propose a concept in which NA discontinuation-associated relapse is an integral part of the stop-to-cure approach and ultimately the trigger for achieving HBsAg loss. Read More

Kansai Medical University.

In the brains of patients with Alzheimer's disease, a decrease in phosphatidylinositol phosphate (PIP) requiring Cl-ATPase activity was found. In cultured rat hippocampal neurons, pathophysiological concentrations of amyloid β proteins (Aβs≤10 nM) lowered PIP levels and Cl-ATPase activity with an increase in intracellular Cl concentrations, resulting in Cl-dependent enhancements in glutamate neurotoxicity and, ultimately, neuronal cell death. Pathophysiological concentrations of Aβs(0. Read More
