These receptors are implicated in several forms of synaptic plasticity – depolarization-induced suppression of excitation (DSE), metabotropic suppression of excitation (MSE), long term depression (LTD) and activation-dependent desensitization. Cultured autaptic hippocampal neurons express all of these, illustrating the rich functional and temporal heterogeneity of CB1 at a single set of synapses. Here we report that coincident activation of muscarinic acetylcholine receptors and elicitation of DSE in autaptic hippocampal neurons results in a substantial (∼40 %) and temporally precise inhibition of excitatory transmission lasting ∼10 minutes. Its induction is blocked by CB1 and muscarinic M3/M5 receptor antagonists and is absent in CB1 receptor knockout neurons. Notably, once it is established, inhibition is reversed by a CB1, but not a muscarinic, antagonist, suggesting that the inhibition occurs via persistent activation of CB1 receptors. We refer to this inhibition as muscarinic cannabinoid suppression of excitation (MCSE). MCSE can be mimicked by coapplication of muscarinic and cannabinoid agonists and requires Ca<sup>2+</sup>-release from internal stores. As such, MCSE represents a novel and targeted form of coincidence detection – important for many modes of learning and memory -- between cannabinoid and muscarinic signaling systems that elicits a medium-duration depression of synaptic signaling. Given the known roles of muscarinic and cannabinoid receptors in the hippocampus, MCSE may be important in the modulation of hippocampal signaling at the site of septal inputs, with potential implications for learning and memory, epilepsy and addiction.</div></div>","PeriodicalId":19918,"journal":{"name":"Pharmacological research","volume":"212 ","pages":"Article 107606"},"PeriodicalIF":9.1,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143009639","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is caused by a progressive degeneration of articular cartilage, causing pain and limited mobility. Among the pathways involved in cartilage homeostasis, “LOX” proteins (referring to three distinct protein families, very often confused in the literature) play a prominent role. The lipoxygenase enzyme family is involved in the inflammatory process of OA by inducing the production of several pro-inflammatory leukotrienes. Lectin-like oxidized low-density lipoprotein family are receptors located at the surface of chondrocytes, which interact with their ligand, ox-LDL, activating several catabolic pathways involved in OA pathophysiology. Finally, lysyl oxidase and lysyl oxidase-like are enzymes expressed intracellularly (in chondrocytes' cytoplasm) involved in elastin biosynthesis and collagen cross-linking in cartilage extracellular matrix. EMA and FDA have not yet approved any drug targeting the LOX proteins. In particular, today lysyl oxidase-like 2 is considered as a new promising target for OA modifying therapy. This review clarifies the main roles of different LOX proteins involved in the progression of OA.

Organ dysfunction includes hepatic involvement, weakening the immune system due to excretory liver failure, and metabolic dysfunction, increasing the death risk. Although experimental studies correlated excretory liver functionality with immune performance and survival rates in sepsis, the proteins and pathways involved remain unclear. This study identified protein kinase C-α (PKCα) as a novel target for managing excretory liver function during sepsis. Using a preclinical murine sepsis model, we found that both PKCα knockout and the use of a PKCα-inhibitor midostaurin successfully restored liver function without hindering the host’s response or ability to clear the pathogen, highlighting PKCα’s vital role in excretory liver failure. In septic animals, both approaches significantly boosted survival rates. Midostaurin is the clinically approved active pharmaceutical ingredient in Rydapt, approved for the adjuvant treatment of FTL3-mutated AML. Here, it reduced plasma bile acids and related inflammation in those patients, opening a translational avenue for therapeutics in sepsis. Conclusively, our research underscores the significance of PKCα in controlling excretory liver function during inflammation. This suggests that targeting this protein could restore liver function without compromising the immune system, thereby decreasing sepsis mortality and supporting the recent paradigm that the liver is a hub for the host response to infection that might, in the future, result in novel host-directed therapies supporting the current state-of-the-art intensive care medicine in patients with sepsis-associated liver failure.</div></div>","PeriodicalId":19918,"journal":{"name":"Pharmacological research","volume":"212 ","pages":"Article 107581"},"PeriodicalIF":9.1,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143034014","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, few studies of cannabis potency effects on cannabis dependence and anxiety have examined gender moderation. Additionally, there are issues with how cannabis potency is calculated via the THC:CBD ratio that may contribute to inconsistencies in the literature. N = 202 (55.8 % women) recent cannabis users (<u>></u>1 g in the past month) with trauma histories – a group at high risk for anxiety and cannabis dependence – completed an online survey including a self-report measure of THC and CBD levels in participants’ typically-used cannabis product.

Cannabis dependence and anxiety levels were self-reported on the Cannabis Use Disorder Identification Test-Revised (CUDIT-R) and Generalized Anxiety Disorder-7 (GAD-7), respectively. Consistent with prior findings in the general population, cannabis potency was significantly positively correlated with cannabis dependence, <em>p</em> = .002, and anxiety levels, <em>p</em> = .020, but only when assessed via THC proportion and not THC:CBD ratio. Consistent with prior research, women reported significantly higher anxiety levels but also unexpectedly, higher THC:CBD ratios, than men. No significant gender differences were found in the associations of either potency measure with either outcome variable.
