Cardiac hypertrophy in mice submitted to a swimming protocol: Influence of training volume and intensity on myocardial renin-angiotensin system.
Soares DdS, Pinto GH, Lopes A, Caetano DSL, Nascimento TG, Andrades ME, Clausell N, Rohde LEP, Leitão SAT, Biolo A (2019) Cardiac hypertrophy in mice submitted to a swimming protocol: Influence of training volume and intensity on myocardial renin-angiotensin system. Am J Physiol Regul Integr Comp Physiol 316(6):R776-R782. doi: 10.1152/ajpregu.00205.2018 PMID: 31042418
Objective: To analyze the cardiac hypertrophy phenotype and the classical and alternative RAS axes in the myocardium of mice submitted to swimming exercises of varying volume and intensity for the development of cardiac hypertrophy.
Summary: Increasing exercise volume and intensity did not induce a pathological hypertrophy phenotype, but instead improved the oxidative capacity, and this process might have the participation of the RAS alternative axis.
Usage: Incubation at 4°C with anti-AT1R diluted in TTBS buffer with 5% non-fat 220 milk 1:800).

Objective: To find missing steps in understanding how peripheral injury instigates central sensitization and the onset of neuropathic pain.
Summary: Colony-stimulating factor 1 (CSF-1) increases excitatory drive to excitatory neurons via a BDNF-dependent mechanism and decreases excitatory drive to inhibitory neurons via BDNF-independent processes.

Objective: To elucidate the role of these serotonergic networks on learned fear and innate panic responses.
Summary: LED excitation or lesioning of PeF projecting 5-HT system respectively attenuated and enhanced panic-associated escape/flight behaviors and cardioexcitation following a 7.5 and 20% CO2 challenge.
Usage: Anti-SERT-SAP was injected into the BLA or PeF to lesion these 5-HT pathways.

Objective: To investigate the underlying mechanisms of STAT3 activation by angiotensin II and downstream functional consequences in the kidneys.
Summary: This study reveals a novel mechanism of STAT3 activation, induced by angiotensin II, in kidney tissues and highlights a translational significance of a STAT3 inhibitor as potential therapeutic agent for hypertensive kidney disease.

Facilitation of neuropathic pain by the NPY Y1 receptor-expressing subpopulation of excitatory interneurons in the dorsal horn.

Objective: To test the relevance of the NPYY1 spinal population to the development and/or maintenance of acute and neuropathic pain.
Summary: This neuroanatomical and behavioral characterization of Y1R-expressing excitatory interneurons provides compelling evidence for the development of spinally-directed Y1R agonists to reduce chronic neuropathic pain.
Usage: Selectively ablated Y1R-expressing interneurons while sparing the central terminals of primary afferents. Rats received intrathecal injections of either NPY-SAP or control Blank-SAP (1000 ng each).

Chemical strategies for antigen-selective targeting of autoreactive B Cells. Chapter 2: Sequential prodrug strategy to target and eliminate ACPA-selective autoreactive B cells.
Lelieveldt L (2019) Chemical strategies for antigen-selective targeting of autoreactive B Cells. Chapter 2: Sequential prodrug strategy to target and eliminate ACPA-selective autoreactive B cells. Radboud Universiteit Nijmegen Nijmegen, Netherlands 45-64. Thesis.
Objective: To develop a method to target and selectively eliminate autoreactive B cells that produce anti-citrullinated proteins antibodies (ACPA) using a sequential antigen prodrug targeting strategy, as a treatment for Rheumatoid Arthritis (RA).
Summary: The study used a synthesized cyclic citrullinated peptide (CCP) antigen suitable for BCR binding and demonstrated that binding by ACPA was impaired upon introduction of a carboxy-pnitrobenzyl (CNBz) caging group at the side chain of the citrulline residue. Enzymatic reduction of the CNBz moiety by nitroreductase fully restored citrulline-selective recognition by both ACPA and ACPA-expressing B cells and showed targeted cell death of CCP-recognizing B cells only. These results mark an important step towards antigen-selective B cell targeting in general and more specifically in RA.
Usage: Streptavidin-ZAP mixed with biotinylated CCP peptides was tested in cytotoxicity assays. The exposure of cells to CCP-SA-ZAP at 1 nM as well as the activated CCP(CNBz) induced death of up to 60% of ACPA-expressing B cells.

Targeted hippocampal GABA neuron ablation by stable substance P-saporin causes hippocampal sclerosis and chronic epilepsy in rats.
Chun E, Bumanglag AV, Burke SN, Sloviter RS (2019) Targeted hippocampal GABA neuron ablation by stable substance P-saporin causes hippocampal sclerosis and chronic epilepsy in rats. Epilepsia 60(5):e52-e57. doi: 10.1111/epi.14723
Objective: Hippocampal GABA neurons were targeted for selective elimination to determine whether a focal hippocampal GABAergic defect in an otherwise normal brain can initiate cryptogenic temporal lobe epilepsy with hippocampal sclerosis.
Summary: Hippocampal GABAergic dysfunction is epileptogenic and can produce the defining features of cryptogenic temporal lobe epilepsy.
Usage: Intrahippocampal injections of SSP-SAP (0.4 ng/10 nL) were performed using a 0.5-μL Neuros Syringe lowered into four hippocampal sites along both the transverse and longitudinal hippocampal axes bilaterally.
