Succinate, traditionally viewed as a mere intermediate of the tricarboxylic acid (TCA) cycle, has emerged critical mediator in inflammation. Disruptions within TCA cycle lead to an accumulation succinate mitochondrial matrix. This excess subsequently diffuses into cytosol and is released extracellular space. Elevated cytosolic levels stabilize hypoxia-inducible factor-1α by inhibiting prolyl hydroxylases, which enhances inflammatory responses. Notably, also acts extracellularly signaling molecule engaging receptor 1 on immune cells, thus modulating their pro-inflammatory or anti-inflammatory activities. Alterations have been associated with various disorders, including rheumatoid arthritis, bowel disease, obesity, atherosclerosis. These associations are primarily due exaggerated cell Given its central role inflammation, targeting pathways offers promising therapeutic avenues for these diseases. paper provides extensive review succinate's involvement processes highlights potential targets future research possibilities development.

Metabolic dysfunction associated with obesity leads to a chronic pro-inflammatory state systemic effects, including the alteration of macrophage metabolism. Tumor-associated macrophages have been linked formation cancer through production metabolites such as itaconate. Itaconate downregulates peroxisome proliferator-activated receptor gamma tumor-suppressing factor and upregulates anti-inflammatory cytokines in M2-like macrophages. Similarly, leptin adiponectin also influence cytokine expression contribute progression colorectal via changes gene within PI3K/AKT pathway. This pathway influences cell proliferation, differentiation, tumorigenesis. work provides review obesity-related hormones inflammatory mechanisms leading development early-onset (EOCRC). A literature search was performed using PubMed Cochrane databases identify studies related EOCRC, keywords 'EOCRC', 'obesity', 'obesity-related hormones', 'itaconate', 'adiponectin', 'leptin', 'M2a macrophage', 'microbiome'. With this concept markers contributing increased use chemo-preventative agents aspirin may protective effect.

Despite advances in antimicrobial and anti-inflammatory treatment, inflammation its consequences remain a major challenge the field of medicine. Inflammatory reactions can lead to life-threatening conditions such as septic shock, while chronic has potential worsen condition body tissues ultimately significant impairment their functionality. Although central nervous system long been considered immune privileged peripheral responses, recent research shown that strong responses periphery also affect brain, leading reactive microglia, which belong innate reside neuroinflammation. The inflammatory response is primarily protective mechanism defend against pathogens tissue damage. However, excessive have negative effects on neuronal structure function. Neuroinflammation underlies pathogenesis many neurological neurodegenerative diseases accelerate progression. Consequently, targeting signaling pathways offers therapeutic strategies for various neuropathological conditions, particularly Parkinson's Alzheimer's disease, by curbing inflammation. Here blood-brain barrier hurdle strategies, therefore it would be highly advantageous foster utilize brain mechanisms. tricarboxylic acid cycle-derived metabolite itaconate upregulated activated macrophages act an immunomodulator with functions. Mesaconate, isomer itaconate, similarly reduces macrophages. Nevertheless, most studies focused esterified forms effects, influence CNS remained largely unexplored. Therefore, this study investigated immunomodulatory endogenously synthesized mesaconate lipopolysaccharide (LPS)-induced neuroinflammatory processes. Our results show both reduce LPS-induced neuroinflammation, evidenced lower levels mediators, reduced microglial reactivity rescue synaptic plasticity, cellular correlate learning memory processes brain. Overall, emphasizes are remarkable importance due endogenous origin production, usually leads high tolerance.

New and emerging pathogens, such as SARS-CoV2 have highlighted the requirement for threat agnostic therapies. Some antibiotics or antivirals can demonstrate broad-spectrum activity against pathogens in same family genus but efficacy quickly reduce due to their specific mechanism of action ability disease causing agent evolve. This has led generation antimicrobial resistant strains, making infectious diseases more difficult treat. Alternative approaches therefore need be considered, which include exploring utility Host-Directed Therapies (HDTs). is a growing area with huge potential difficulties arise complexity profiles. For example, HDT given early during infection may not appropriate effective when become chronic patient intensive care. With understanding immune function, new treatment could allow targeting pathways augment diminish host response, dependent upon profile, bespoke therapeutic management plans. review highlights promising approved HDTs that manipulate system throughout spectrum disease, particular viral bacterial demonstrates how advantages will soon outweigh side 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.
