Endogenous µ-opioid receptor activity in the lateral and capsular subdivisions of the right central nucleus of the amygdala prevents chronic postoperative pain.

J Neurosci Res 2021 May 6. Epub 2021 May 6.

Department of Anesthesiology and Perioperative Medicine, Pittsburgh Center for Pain Research, Pittsburgh Project to End Opioid Misuse, University of Pittsburgh, Pittsburgh, PA, USA.

Tissue injury induces a long-lasting latent sensitization (LS) of spinal nociceptive signaling that is kept in remission by an opposing µ-opioid receptor (MOR) constitutive activity. To test the hypothesis that supraspinal sites become engaged, we induced hindpaw inflammation, waited 3 weeks for mechanical hypersensitivity to resolve, and then injected the opioid receptor inhibitors naltrexone, CTOP or β-funaltrexamine subcutaneously, and/or into the cerebral ventricles. Intracerebroventricular injection of each inhibitor reinstated hypersensitivity and produced somatic signs of withdrawal, indicative of LS and endogenous opioid dependence, respectively. Read More

Interleukin-23 reshapes kidney resident cell metabolism and promotes local kidney inflammation.

J Clin Invest 2021 May 6. Epub 2021 May 6.

Department of Medicine, Beth Israel Deaconess Medical Center, Boston, United States of America.

Interstitial kidney inflammation is present in various nephritides in which serum IL-23 is elevated. Here we show that IL-23 receptor (IL-23R) expressing murine and human renal tubular epithelial cells (TEC) respond to IL-23 by inducing intracellular calcium flux, enhanced glycolysis, and the upregulation of calcium/calmodulin kinase IV (CaMK4) which results in suppression of the expression of the arginine degrading enzyme arginase 1 (ARG1) thus increasing in situ levels of free L-Arginine (Arg). Limited availability of Arg suppresses the ability of infiltrating T cells to proliferate and produce inflammatory cytokines. Read More

[BRAF-V600E testing in metastatic colorectal cancer and new, chemotherapy-free therapy options. German version].

Pathologe 2021 May 6. Epub 2021 May 6.

Klinik für Gastroenterologie, Hepatologie und Endokrinologie, Medizinische Hochschule Hannover, Hannover, Deutschland.

In the past 25 years, treatment of metastatic colorectal cancer (mCRC) has undergone profound changes. The approval of newer chemotherapeutics such as irinotecan and oxaliplatin was followed in 2005 by the first targeted therapies, for example, monoclonal antibodies directed against the epidermal growth factor receptor (EGFR), as cetuximab and panitumumab, or the angiogenesis inhibitors bevacizumab, ramucirumab, and aflibercept. With the rapidly progressing molecular characterization of mCRC in the last 10 years and the classification of the disease in four consensus subtypes, further changes are emerging, which will promote, among other things, the introduction of protein-kinase inhibitors developed for specific molecular aberrations as well as immune checkpoint inhibitors into the treatment algorithm.
