Huang L, Tao Y, Wu X, Wu J, Shen M, Zheng Z. The role of NLRP12 in inflammatory diseases. Eur J Pharmacol 2023; 956:175995. [PMID: 37572944 DOI: 10.1016/j.ejphar.2023.175995] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2023] [Revised: 08/04/2023] [Accepted: 08/10/2023] [Indexed: 08/14/2023]
Abstract
Nucleotide-binding leucine-rich repeat-containing receptor 12 (NLRP12), a highly conserved protein containing an N-terminal pyrin domain (PYD), a nucleotide-binding domain and a C-terminal leucine-rich repeat region, belongs to the nucleotide-binding oligomerization domain-like receptor-containing PYD (NLRP) family and is a cytoplasmic sensor that plays a negative role in inflammation. NLRP12 is involved in multiple disease processes, including formation of inflammasomes and regulation of both canonical and noncanonical inflammatory signaling pathways. NLRP12 and pathogenic infections are closely linked, and alterations in NLRP12 expression and activity are associated with inflammatory diseases. In this review, we begin with a summary of the mechanisms of negative regulation by NLRP12. We then underscore the important roles of NLRP12 in the onset and progression of inflammation, infectious disease, host defense, carcinogenesis and COVID-19. Finally, we highlight factors that influence NLRP12 activity, including synthetic and naturally derived agonists, and are regarded as potential therapeutic agents to overcome inflammatory diseases.

Management of depression in patients with coronary artery disease: A systematic review. Asian J Psychiatr 2023; 83:103534. [PMID: 36871435 DOI: 10.1016/j.ajp.2023.103534] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/22/2022] [Revised: 02/14/2023] [Accepted: 02/24/2023] [Indexed: 03/06/2023]
Abstract
Depression is an independent risk factor for coronary artery disease (CAD). Both illnesses contribute significantly to the global burden of disease. This systematic literature review examines treatment interventions for CAD patients with comorbid depression. We systematically reviewed The Cochrane Library, MEDLINE, EMBASE, PsycINFO, PUBMED, CINAHL and the ISRCTN Registry for English language randomised control trials investigating treatment interventions for depression in adults with CAD and comorbid depression. Data extracted included author name(s), year published, number of participants, enrolment criteria, depression definition/measures (standardised interviews, rating scales), description of control arms and interventions (psychotherapy and/or medications), randomisation, blinding, follow-up duration, follow-up loss, depression scores and medical outcome. The database search revealed 4464 articles. The review yielded 19 trials. Antidepressant and/or psychotherapy did not significantly influence CAD outcomes in the overall population. There was no difference between antidepressant use and aerobic exercises. Psychological interventions and pharmacological interventions provide small effect on depression outcomes in CAD patients. Patient autonomy in choice of treatment is associated with greater depression treatment satisfaction, but the majority of studies are underpowered. More research is required to explore the role of neurostimulation treatment, complementary and alternative treatments.

Abstract
Consistent evidence from observational studies supports a risk-increasing association between post-traumatic stress disorder (PTSD) and coronary artery disease (CAD); however, the mechanisms underlying their relationship remain poorly understood. This study assesses the genetic correlation and potential causal relationship between PTSD and CAD-related traits. We analysed genome-wide associated study summary data of PTSD (cases = 23,212, controls = 151,447) with CAD-related traits (sample size up to 408,458 individuals) to achieve our study objectives. Findings revealed a significant and positive genetic correlation between PTSD and CAD (rG = 0.19, p = 3.47 × 10-2), and between PTSD and CAD traits of ischemic heart disease (genetic correlation [rG] = 0.42, p = 5.17 × 10-10), coronary arteriosclerosis (rG = 0.32, p = 3.78 × 10-7), and angina pectoris (rG = 0.48, p = 1.14 × 10-9). However, Mendelian randomisation (MR) analysis found no evidence for a significant causal association between PTSD and CAD traits, regardless of analysis direction (PTSD or CAD traits as the exposure or outcome variable). Findings from MR sensitivity analyses were consistent, suggesting that genetic liability to PTSD has no causal influence on any CAD trait and vice versa. In summary, our study provides evidence implicating a positive genetic correlation between PTSD with CAD-related traits, supporting evidence of a risk-increasing but non-causal association between them.

Abstract
BACKGROUND Although the genetic factors associated with hypertension remain unknown, genetic variations in genes related to ion channels, inflammation, and the cell cycle may affect susceptibility to hypertension. In the present study, the association between hypertension and 10 candidate single-nucleotide polymorphisms (SNPs) was evaluated among Chinese Dai people, who have a smaller gene pool than Han individuals. METHODS A total of 1,193 samples from Dai people were collected, including 488 with hypertension and 705 with normal blood pressure. Based on the preliminary results of whole-genome sequencing among pools of individuals (Pool-seq), 10 candidate SNPs in 6 genes (FAM110D, ADD1, RAG1, CACNA1C, CACNA1A, and NLRP12) were genotyped in the case and control groups by multiplex PCR for SNP genotyping with next-generation sequencing (MultiPCR-NGS). The relationship between hypertension and each candidate SNP was evaluated using the χ 2 test and multiple logistic regression analysis. RESULTS The χ 2 test showed that the allele frequencies of rs3748856 in FAM110D, rs139118504 in CACNA1A, and rs34436714 in NLRP12 were significantly different between the case and control groups (P < 0.005). After adjusting for age, body mass index, total cholesterol, triglyceride, and low-density lipoprotein, logistic regression analyses revealed that the association between the 3 SNPs and hypertension among Dai people remained significant (P = 0.012, 2.71 × 10-4, and 0.017, respectively). CONCLUSIONS These findings indicate that there may be different molecular pathogeneses of hypertension among Dai people, which should be noted in future studies.

Disentangling the Molecular Mechanisms of the Antidepressant Activity of Omega-3 Polyunsaturated Fatty Acid: A Comprehensive Review of the Literature. Int J Mol Sci 2021; 22:ijms22094393.

Abstract
Major depressive disorders (MDDs) are often associated with a deficiency in long-chain omega-3 polyunsaturated fatty acids (ω-3 PUFAs), as well as signs of low-grade inflammation. Epidemiological and dietary studies suggest that a high intake of fish, the major source of ω-3 PUFAs, is associated with lower rates of MDDs. Meta-analyses of randomized placebo-controlled ω-3 PUFAs intervention-trials suggest that primarily eicosapentaenoic acid (EPA), but not docosahexaenoic acid (DHA), is responsible for the proposed antidepressant effect. In this review, we dissect the current biological knowledge on EPA and DHA and their bioactive lipid metabolites to search for a pharmacological explanation of this, to date, unexplained clinical observation. Through enzymatic conversion by cyclooxygenase (COX), lipoxygenase (ALOX), and cytochrome P-450 monooxygenase (CYP), EPA and DHA are metabolized to major anti-inflammatory and pro-resolving lipid mediators. In addition, both ω-3 PUFAs are precursors for endocannabinoids, with known effects on immunomodulation, neuroinflammation, food intake and mood. Finally, both ω-3 PUFAs are crucial for the structure and organization of membranes and lipid rafts. While most biological effects are shared by these two ω-3 PUFAs, some distinct features could be identified: (1) The preferential CYP monooxygenase pathway for EPA and EPA derived eicosanoids; (2) The high CB2 receptor affinities of EPA-derived EPEA and its epoxy-metabolite 17,18-EEQ-EA, while the DHA-derived endocannabinoids lack such receptor affinities; (3) The competition of EPA but not DHA with arachidonic acid (AA) for particular glycerophospholipids. EPA and AA are preferentially incorporated into phosphatidylinositols, while DHA is mainly incorporated into phosphatidyl-ethanolamine, -serine and -choline. We propose that these distinct features may explain the superior antidepressant activity of EPA rich ω-3 PUFAs and that these are potential novel targets for future antidepressant drugs.

Abstract
Although the global incidence of neurodegenerative diseases has been steadily increasing, especially in adults, there are no effective therapeutic interventions. Neurodegeneration is a heterogeneous group of disorders that is characterized by the activation of immune cells in the central nervous system (CNS) (e.g., mast cells and microglia) and subsequent neuroinflammation. Mast cells are found in the brain and the gastrointestinal tract and play a role in "tuning" neuroimmune responses. The complex bidirectional communication between mast cells and gut microbiota coordinates various dynamic neuro-cellular responses, which propagates neuronal impulses from the gastrointestinal tract into the CNS. Numerous inflammatory mediators from degranulated mast cells alter intestinal gut permeability and disrupt blood-brain barrier, which results in the promotion of neuroinflammatory processes leading to neurological disorders, thereby offsetting the balance in immune-surveillance. Emerging evidence supports the hypothesis that gut-microbiota exert a pivotal role in inflammatory signaling through the activation of immune and inflammatory cells. Communication between inflammatory cytokines and neurocircuits via the gut-brain axis (GBA) affects behavioral responses, activates mast cells and microglia that causes neuroinflammation, which is associated with neurological diseases. In this comprehensive review, we focus on what is currently known about mast cells and the gut-brain axis relationship, and how this relationship is connected to neurodegenerative diseases. We hope that further elucidating the bidirectional communication between mast cells and the GBA will not only stimulate future research on neurodegenerative diseases but will also identify new opportunities for therapeutic interventions.

Systemic Catecholaminergic Deficiency in Depressed Patients with and without Coronary Artery Disease. J Clin Med 2021; 10:jcm10050986.

Abstract
Background: Stress and depression are known to contribute to coronary artery disease (CAD) with catecholamines (CA), altering the balance to a pro- and anti-inflammatory stetting and potentially playing a key role in the underlying pathophysiology. This study aimed to elucidate the impact of social stress on the CA system and inflammation markers in patients suffering from CAD and depression. Methods: 93 subjects were exposed to the Trier Social Stress Test (TSST). Based on the results of the depression subscale of the Hospital Anxiety and Depression Scale (HADS, German Version) and the presence/absence of CAD, they were divided into four groups. A total of 21 patients suffered from CAD and depression (+D+CAD), 26 suffered from CAD alone (−D+CAD), and 23 suffered from depression only (+D−CAD); another 23 subjects served as healthy controls (−D−CAD). Subjects were registered at 09:00 AM at the laboratory. A peripheral venous catheter was inserted, and after a 60-min-resting period, the TSST was applied. Prior to and 5, 15, 30, and 60 min after the stress test, plasma epinephrine, norepinephrine, and dopamine concentrations (High Performance Liquid Chromatography (HPLC)) were measured together with the inflammation markers interleukin-6 (IL-6) and monocyte chemotactic protein-1 (MCP-1). High-sensitive C-reactive protein (hs-CRP, Enzyme-linked Immunosorbent Assay (ELISA)) was measured prior to TSST. Results: (+D−CAD) and (+D+CAD) patients showed significantly lower epinephrine and dopamine levels compared to the (−D+CAD) and (−D−CAD) participants at baseline (prior to TSST). Over the whole measurement period after the TSST, no inter-group difference was detected. Partial correlation (controlling for age, gender and Body Mass Index (BMI)) revealed a significant direct relation between MCP-1 and norepinephrine (r = 0.47, p = 0.03) and MCP-1 and epinephrine (r = 0.46, p = 0.04) in patients with −D+CAD at rest. Conclusions: The stress response of the CA system was not affected by depression or CAD, whereas at baseline we detected a depression-related reduction of epinephrine and dopamine release independent of CAD comorbidity. Reduced norepinephrine and dopamine secretion in the central nervous system in depression, known as ‘CA-deficit hypothesis’, are targets of antidepressant drugs. Our results point towards a CA-deficit in the peripheral nervous system in line with CA-deficit of the central nervous system and CA exhaustion in depression. This might explain somatic symptoms such as constipation, stomach pain, diarrhoea, sweating, tremor, and the influence of depression on the outcome of somatic illness such as CAD.

Abstract
Posttraumatic stress disorder (PTSD) is a highly disabling condition associated with alterations in multiple neurobiological systems, including increases in inflammatory function. Vagus nerve stimulation (VNS) decreases inflammation, however few studies have examined the effects of non-invasive VNS on physiology in human subjects, and no studies in patients with PTSD. The purpose of this study was to assess the effects of transcutaneous cervical VNS (tcVNS) on inflammatory responses to stress. Thirty subjects with a history of exposure to traumatic stress with (N = 10) and without (N = 20) PTSD underwent exposure to stressful tasks immediately followed by active or sham tcVNS and measurement of multiple biomarkers of inflammation (interleukin-(IL)-6, IL-2, IL-1β, Tumor Necrosis Factor alpha (TNFα) and Interferon gamma (IFNγ) over multiple time points. Stressful tasks included exposure to personalized scripts of traumatic events on day 1, and public speech and mental arithmetic (Mental Stress) tasks on days 2 and 3. Traumatic scripts were associated with a pattern of subjective anger measured with Visual Analogue Scales and increased IL-6 and IFNγ in PTSD patients that was blocked by tcVNS (p < .05). Traumatic stress had minimal effects on these biomarkers in non-PTSD subjects and there was no difference between tcVNS or sham. No significant differences were seen between groups in IL-2, IL-1β, or TNFα. These results demonstrate that tcVNS blocks behavioral and inflammatory responses to stress reminders in PTSD.

Abstract
Introduction: There has long been an interest in the effects of diet on mental health, and the interaction of the two with stress; however, the nature of these relationships is not well understood. Although associations between diet, obesity and the related metabolic syndrome (MetS), stress, and mental disorders exist, causal pathways have not been established. Methods: We reviewed the literature on the relationship between diet, stress, obesity and psychiatric disorders related to stress. Results: Diet and obesity can affect mood through direct effects, or stress-related mental disorders could lead to changes in diet habits that affect weight. Alternatively, common factors such as stress or predisposition could lead to both obesity and stress-related mental disorders, such as depression and posttraumatic stress disorder (PTSD). Specific aspects of diet can lead to acute changes in mood as well as stimulate inflammation, which has led to efforts to assess polyunsaturated fats (PUFA) as a treatment for depression. Bidirectional relationships between these different factors are also likely. Finally, there has been increased attention recently on the relationship between the gut and the brain, with the realization that the gut microbiome has an influence on brain function and probably also mood and behavior, introducing another way diet can influence mental health and disorders. Brain areas and neurotransmitters and neuropeptides that are involved in both mood and appetite likely play a role in mediating this relationship. Conclusions: Understanding the relationship between diet, stress and mood and behavior could have important implications for the treatment of both stress-related mental disorders and obesity.

Abstract
Major depressive disorder (MDD) is a psychiatric condition that affects a large number of people in the world, and the treatment existents do not work for all individuals affected. Thus, it is believed that other systems or pathways which regulate brain networks involved in mood regulation and cognition are associated with MDD pathogenesis. Studies in humans and animal models have been shown that in MDD there are increased levels of inflammatory mediators, including cytokines and chemokines in both periphery and central nervous system (CNS). In addition, microglial activation appears to be a key event that triggers changes in signaling cascades and gene expression that would be determinant for the onset of depressive symptoms. Recent researches also point out that changes in the gut microbiota would lead to a systemic inflammation that in different ways would reach the CNS modulating inflammatory pathways and especially the microglia, which could influence responses to treatments. Moreover, pre- and probiotics have shown antidepressant responses and anti-inflammatory effects. This review will focus on studies that show the relationship of inflammation with the gut microbiota-brain axis and its relation with MDD.
