Microglia, the resident immune cells of central nervous system (CNS), play a crucial role in maintaining tissue homeostasis by monitoring and responding to environmental changes through processes such as phagocytosis, cytokine production or synapse remodeling. Their dynamic nature diverse functions are supported regulation multiple metabolic pathways, enabling microglia efficiently adapt fluctuating signals. A key aspect this occurs at mitochondria-associated ER membranes (MAM), specialized contact sites between mitochondria. These structures facilitate exchange calcium, lipids, metabolites serve signaling hubs. This review synthesizes current research on how MAM influence microglial physiology, with an emphasis their immunometabolism, offering new insights into integration CNS its impact context neurodegeneration.

The innate immune system serves as the body's first line of defense, utilizing pattern recognition receptors like Toll-like to detect pathogens and initiate rapid response mechanisms. Following this initial response, adaptive immunity provides highly specific sustained killing via B cells, T antibodies. Traditionally, it has been assumed that activates immunity; however, recent studies have revealed more complex interactions. This review a detailed dissection composition function systems, emphasizing their synergistic roles in physiological pathological contexts, providing new insights into link between these two forms immunity. Precise regulation both systems at same time is beneficial fight against immune-related diseases, for example, cGAS-STING pathway found play an important role infections cancers. In addition, paper summarizes challenges future directions field immunity, including latest single-cell sequencing technologies, CAR-T cell therapy, checkpoint inhibitors. By summarizing developments, aims enhance our understanding complexity interactions perspectives system.

Abstract Alzheimer’s disease (AD) involves a dynamic interaction between neuroinflammation and metabolic dysregulation, where microglia play central role. These immune cells undergo reprogramming in response to AD-related pathology, with key genes such as TREM2, APOE, HIF-1α orchestrating these processes. Microglial metabolism adapts environmental stimuli, shifting oxidative phosphorylation glycolysis. Hexokinase-2 facilitates glycolytic flux, while AMPK acts an energy sensor, coordinating lipid glucose metabolism. TREM2 APOE regulate microglial homeostasis, influencing Aβ clearance responses. LPL ABCA7, both associated AD risk, modulate processing cholesterol transport, linking neurodegeneration. PPARG further supports by regulating inflammatory Amino acid also contributes function. Indoleamine 2,3-dioxygenase controls the kynurenine pathway, producing neurotoxic metabolites linked pathology. Additionally, glucose-6-phosphate dehydrogenase regulates pentose phosphate maintaining redox balance activation. Dysregulated metabolism, influenced genetic variants APOE4, impair responses exacerbate progression. Recent findings highlight interplay regulators like REV-ERBα, which modulates inflammation, Syk, influences clearance. insights offer promising therapeutic targets, including strategies aimed at modulation, could restore function depending on stage. By integrating metabolic, immune, factors, this review underscores importance of immunometabolism AD. Targeting pathways provide novel for mitigating restoring function, ultimately paving way innovative treatments neurodegenerative diseases.

The extracellular matrix (ECM) plays a central role in the structural integrity and functionality of cardiovascular system. Moreover, ECM is involved atherosclerotic plaque formation stability. In fact, remodeling affects stability, cellular migration, inflammatory responses. Collagens, fibronectin, laminin, elastin, proteoglycans are crucial proteins during atherosclerosis development. This dynamic driven by proteolytic enzymes such as metalloproteinases (MMPs), cathepsins, serine proteases. Exploring investigating dynamics an important step to designing innovative therapeutic strategies targeting mechanisms, thus offering significant advantages management diseases. review illustrates structure vascular ECM, presenting new perspective on its potential target treatments.

Necroptosis is a crucial modality of programmed cell death characterized by distinct morphological and biochemical hallmarks, including membrane rupture, organelle swelling, cytoplasmic nuclear disintegration, cellular contents leakage, release damage-associated molecular patterns (DAMPs), accompanied the inflammatory responses. Studies have shown that necroptosis involved in etiology evolution variety pathologies organ damage, inflammation disorders, cancer. Despite its significance, field research grapples with challenge non-standardized detection methodologies. In this review, we introduce fundamental concepts mechanisms critically appraise principles, merits, inherent limitations current technologies. This endeavor seeks to establish methodological framework for detection, thereby propelling deeper insights into necroptosis.

Tumors can exert a far-reaching influence on the body, triggering systemic responses that contribute to debilitating conditions like cancer cachexia. To characterize mechanisms underlying tumor-host interactions, we utilized BioID-based proximity labeling method identify proteins secreted by Yki act adult Drosophila gut tumors into bloodstream/hemolymph. Among major identified are coagulation and immune-responsive factors wasting phenotypes associated with tumors. The effect of innate immunity is mediated NFκB transcription Relish, dorsal, Dif, which in turn upregulate expression cachectic Pvf1, Impl2, Upd3. In addition, secrete Eiger, TNF-alpha homolog, activates JNK signaling pathway neighboring non-tumor cells, leading cell death. release damage-associated molecular patterns (DAMPs) from these dying cells presumably amplifies inflammatory response, exacerbating wasting. Targeting pathway, or production could potentially alleviate effects

In inflammatory bowel diseases (IBD), the most promising therapies targeting cytokines or immune cell trafficking demonstrate around 40% efficacy. As IBD is a multifactorial inflammation of intestinal tract, single-target approach unlikely to solve this problem, necessitating an alternative strategy that addresses its variability. One often overlooked by pharmaceutically driven therapeutic options address impact environmental factors. This somewhat surprising considering increasingly viewed as condition heavily influenced such factors, including diet, stress, and pollution-often referred "Western lifestyle". IBD, responses result from complex interplay among genetic background patient, molecules, cells, local microenvironment where danger- microbe-associated molecular patterns (D/MAMPs) provide adjuvant-rich environment. Through activating DAMP receptors, array pro-inflammatory factors can stimulate, for example, NLRP3 inflammasome-a major amplifier response in various cells via non-specific bystander activation myeloid (e.g., macrophages) lymphocytes tissue-resident memory T cells). Current biological treatment approaches dampen response, but without reducing exposure e.g., changing diet (reducing ultra-processed foods), landscape never resolved continues drive mucosal dysregulation. Thus, are not enough put out fire. The resultant smoldering, low-grade diminishes physiological resilience (micro)environment, perpetuating state chronic disease. Therefore, our hypothesis posits successful interventions must complexity disease simultaneously all modifiable aspects: innate immunity microbiota, adaptive cytokines, relate (micro)environment. Thus be comprehensively treated across nano-, meso-, microscales, rather than with focus on single targets. A broader perspective also includes adapt DAMPing (micro)environment warranted.
