Aggregata polibraxiona d. sp. (Apicomplexa: Aggregatidae) from Octopus bimaculatus Verrill, 1883 (Mollusca: Cephalopoda) from the Gulf of mexico associated with Los angeles, Mexico.
Respiratory airway, blood vessel and intestinal wall remodeling, in which smooth muscle remodeling plays a major role, is a key pathological event underlying the development of several associated diseases, including asthma, cardiovascular disorders (e.g., atherosclerosis, hypertension, and aneurism formation), and inflammatory bowel disease. However, the mechanisms underlying these remodeling processes remain poorly understood. We hypothesize that the creation of chronic inflammation-mediated networks that support and exacerbate the airway, as well as vascular and intestinal wall remodeling, is a crucial pathogenic mechanism governing the development of the associated diseases. The failed inflammation resolution might be one of the causal pathogenic mechanisms. Hence, it is reasonable to assume that applying specialized, pro-resolving mediators (SPMs), acting via cognate G-protein coupled receptors (GPCRs), could potentially be an effective pathway for treating these disorders. However, several obstacles, such as poor understanding of the SPM/receptor signaling pathways, SMP rapid inactivation as well as their complex and costly synthesis, limit their translational potential. In this connection, stable, small-molecule SPM mimetics and receptor agonists have emerged as new, potentially suitable drugs. It has been recently shown in preclinical studies that they can effectively attenuate the manifestations of asthma, atherosclerosis and Crohn's disease. Remarkably, some biased SPM receptor agonists, which cause a signaling response in the desired inflammation pro-resolving direction, revealed similar beneficial effects. Adenine sulfate chemical These encouraging observations suggest that SPM mimetics and receptor agonists can be applied as a novel approach for the treatment of various chronic inflammation conditions, including airway, vascular and intestinal wall remodeling-associated disorders.Immune and glial cells play a pivotal role in chronic pain. Therefore, it is possible that the pharmacological modulation of neurotransmission from an exclusively neuronal perspective may not be enough for adequate pain management, and the modulation of complex interactions between neurons and other cell types might be needed for successful pain relief. In this article, we review the current scientific evidence for the modulatory effects of sigma-1 receptors on communication between the immune and nervous systems during inflammation, as well as the influence of this receptor on peripheral and central neuroinflammation. Several experimental models of pathological pain are considered, including peripheral and central neuropathic pain, osteoarthritic, and cancer pain. Sigma-1 receptor inhibition prevents peripheral (macrophage infiltration into the dorsal root ganglion) and central (activation of microglia and astrocytes) neuroinflammation in several pain models, and enhances immune-driven peripheral opioid analgesia during painful inflammation, maximizing the analgesic potential of peripheral immune cells. Therefore, sigma-1 antagonists may constitute a new class of analgesics with an unprecedented mechanism of action and potential utility in several painful disorders.Psychiatric disorders represent a critical challenge to our society, given their high global prevalence, complex symptomatology, elusive etiology and the variable effectiveness of pharmacological therapies. Recently, there has been a shift in investigating and redefining these diseases by integrating behavioral observations and multilevel neurobiological measures. Accordingly, endophenotype-oriented studies are needed to develop new therapeutic strategies, with the idea of targeting shared symptoms instead of one defined disease. With these premises, here we investigated the therapeutic properties of chronic treatment with the second-generation antipsychotic blonanserin in counteracting the alterations caused by 7 weeks of Chronic Mild Stress (CMS) in the rat. CMS is a well-established preclinical model able to induce depressive and anxiety-like alterations, which are shared by different psychiatric disorders. Our results demonstrated that the antipsychotic treatment normalizes the CMS-induced emotionality deficits, an effect that may be due to its ability in modulating, within the prefrontal cortex, redox mechanisms, a molecular dysfunction associated with several psychiatric disorders. These evidences provide new insights into the therapeutic properties and potential use of blonanserin as well as in its mechanisms of action and provide further support for the role of oxidative stress in the pathophysiology of psychiatric disorders.Based on the role of ATG7 in the initiation of autophagy, autophagy can be divided into ATG7-dependent selective autophagy and ATG7-independent alternative autophagy. However, the detailed roles of two different types of autophagy in antitumor therapy have not been fully elucidated so far. Here, we for the first time demonstrated an investigational inducer, w09, could induce both selective autophagy and alternative autophagy in NSCLC, but the phenotypes of these two kinds of autophagy are different:(1) w09-induced selective autophagy mainly promoted cell apoptosis, while w09-triggered alternative autophagy markedly induced autophagic cell death in NSCLC;(2) w09-induced ATG7 dependent autophagy mainly promoted the accumulation of SQSTM1/p62, while w09-triggered ATG7 independent autophagy markedly accelerated the degradation of SQSTM1/p62. These above results were further confirmed by knockout ATG7 gene in A549 cells or restoration of ATG7 function in H1650 cells. Deletion of ATG7 gene markedly attenuated the effect of w09-induced autophagy or apoptosis on A549 cells, while restoration of functional ATG7 markedly enhanced the effect of w09-induced autophagy and apoptosis on H1650 cells. Mechanistically, we further revealed that w09 induced two different types of autophagy through inhibiting PI3K/AKT/mTOR signaling pathway. Notably, compared with A549WT xenograft model, the in vivo antitumor effect of w09 or Taxel on the ATG7-deficient A549 xenograft model was significantly attenuated. Therefore, a special attention must be paid to distinguish which kinds of autophagy have been induced by autophagy inducers with antitumor agents by targeting PI3K/AKT/mTOR signaling pathway.
