BACKGROUND: Millions of cells in multicellular organisms regenerate every day to replace aged and died cells. Effective cell clearance (efferocytosis) is critical for tissue homeostasis, as the human body recycles its cellular components. We summarize what is known about the mechanisms of efferocytosis and how it impacts the physiology of the organism, effects on inflammation and the adaptive immune response, as well as the consequences of defects in this critical homeostatic mechanism in this review.CONTENT: Cell death is the process by which the human body replaces aged or damaged cells with new ones. It can be triggered by genetically encoded machinery or regulated cell death, or by specific pharmacologic or genetic interventions, resulting in accidental cell death. Dying cells release signals that entice phagocytes to engulf them in a process known as efferocytosis. Efferocytosis is a multistep process involving the release of “find me” and “eat me” signals and destruction of death cells by phagocytes. Different types of cell death including apoptosis and necroptosis can express pro- or anti-inflammatory signals via macrophage activity modulation.SUMMARY: Failed or ineffective efferocytosis can result in disruption of tissue homeostasis, which can contribute to the development of chronic inflammatory diseases such as atherosclerosis, obesity, diabetes, and heart failure. Therefore, any therapeutic strategy that enhances efferocytosis will have a beneficial effect on the treatment of these metabolic disorders.KEYWORDS: apoptosis, necroptosis, phagocytosis, efferocytosis, macrophage.

BACKGROUND: Aging tissues lose their homeostatic and regenerative capacities, which has been linked to the degeneration of the stem cells such as the tissue-specific stem cells, the stem cell niches, and systemic cues that regulate stem cell activity.CONTENT: The maintenance of tissue homeostatic and regeneration dependent on its tissue-specific stem cells, that —long-lived cells with the ability to self-renew and differentiate into mature cells. Understanding the molecular mechanisms that governs stem cell survival, self-renewal, quiescence, proliferation, and commitment to specific differentiated cell lineages is critical for identifying the drivers and effectors of age-associated stem cell failure. Such understanding will be critical for the development of therapeutic approaches that can decrease, and possibly reverse and repair the age-related degenerative process in aging tissues.SUMMARY: The exact mechanisms and reasons of aging process were not fully elucidated until now. Stem cells is one of the keys for maintaining tissues heath and understanding how stem cell decline with age will give us opportunities to find strategy in increasing somatic stem cells regenerative capacity and delay the aging process.KEYWORDS: adult stem cell, aging, epigenetic, metabolism, quiescence, senescence

BACKGROUND: Aging is an unavoidable part of life, defined by a gradual loss in tissue and organ function and an increasing chance of death. Current studies of aging connected the genetic and epigenetic changes to cause this process.CONTENT: When the aging-related epigenetic alterations is accumulated, it may result in irregulated gene expression, metabolic instability, stem cell senescence and exhaustion, and imbalance of tissue homeostasis, which all accelerate the aging process. Altered epigenetic gene regulatory mechanisms such as DNA methylation, histone modification and chromatin remodeling, and non-coding RNAs can induce aging process, thus manipulating these processes give a chance for the success of age-delaying interventions.SUMMARY: Given updated tools and technologies to investigate the epigenetic regulation affecting aging processes, new therapeutic strategies to delay this process can be developed to increase longevity and improve quality of life.KEYWORDS: aging, epigenetic, senescence, autophagy, mitochondria, metabolism, rejuvenation

BACKGROUND: Obesity incidence has risen dramatically during the last 50 years, reaching epidemic proportions. Obesity's growing prevalence, as well as its numerous metabolic and cardiovascular problems, poses a danger to human health and lifespan across the world.CONTENT: Numerous studies have shown that obesity causes inflammation, and suggest that inflammation may have a causal role in the development of insulin resistance, defective insulin secretion, and energy homeostasis disturbance. Obesity-induced inflammation is different from other inflammatory models because it includes tonic activation of the innate immune system, which has a long-term influence on metabolic balance. Inflammation can cause tissue damage by causing maladaptive responses such as fibrosis and necrosis. Obesity-induced inflammation is unique since it affects a variety of organs, including the adipose tissue, pancreas, liver, skeletal muscle, heart, and brain. These characteristics of obesity-induced inflammation make it difficult to decipher the underlying processes and how they affect metabolic systems.SUMMARY: The disruption of energy homeostasis caused by a positive energy balance is most likely the first trigger of metabolic inflammation, and the initial adaptive response aim to relieve the anabolic pressure caused by obesity. However, over time, this adaptive reaction becomes maladaptive, and the persistence of inflammation shows that the initial response has failed. The inflammation affects so many organ systems during obesity, and to develop novel treatment methods, a greater knowledge of the process was needed.KEYWORDS: obesity, inflammation, diabetes mellitus, non-alcoholic fatty liver disease, cardiovascular diseases, heart failure

BACKGROUND: Metabolism impairment in obese condition usually initially triggered by inflammation and insulin signaling impairment. The involvement of metabolites, including lipids, amino acids, and ketone bodies, in altering insulin sensitivity has been revealed after massive data sets were provided by the studies regarding metabolomics and lipidomics.CONTENT: Metabolites were now understood to serve more than just the metabolism products, but also as active signaling molecules including in insulin and immunological actions. Different lipid metabolites can serve as signaling molecules to induce insulin resistance of sensitivity through a similar pathway, and impact on the inflammation status. Branched Chain Amino Acids (BCAA) and many amino acids have been correlated with mitochondrial dysfunction and insulin impairment. Ketogenic diet, supplementation and microbiota transplantation become the current strategies to set a preferable metabolites composition to modulate insulin sensitivity.SUMMARY: Thousands of metabolites can now be measured using technical and bioinformatics developments. Different types of amino acids, fatty acids, and bile acids are being studied in relation to altered metabolic states, particularly obesity and type 2 diabetes mellitus. A thorough knowledge of the metabolic changes that contribute to insulin resistance might lead to the discovery of new targets for enhancing insulin sensitivity and preventing and treating many metabolic disorders.KEYWORDS: metabolites, insulin resistance, lipids, amino acids, ketone bodies

BACKGROUND: Many chronic disorders, including vascular diseases, metabolic syndrome, and neurological diseases, are known to share a common factor of excessive inflammation. It takes a lot of energy to heal damaged tissue, which is a complicated process. The outcome is often suboptimal, with some degree of fibrosis, depending on the tissue's ability to regenerate and the strength of the inflammatory response. We may get new insights into disease causation and therapeutic strategies by better understanding endogenous regulatory points within the inflammatory response.CONTENT: Despite of the benefit in raising an inflammatory response, it also have unfavourable effects. Unresolved inflammation can over accumulate collagenous connective tissue and induce fibrosis, promote tissue dysfunction, and finally organ failure. Currently, the resolution of inflammation was described in terms of contemporary molecules as a different mechanisms from anti-inflammatory, since in resolution, the pathogen and apoptotic cells crumbs will be cleared and the macrophages will set back the tissue homeostasis. An active transition in the mediators that predominate in exudates occurs in conjunction with the remission of inflammation. These groups of inborn pro-resolution named resolvins, maresins, and protectins work to reduce inflammation by triggering certain pathways that support homeostasis rather than by suppressing the immune system.SUMMARY: The resolution of inflammation, once believed to be a passive process, is now understood to entail active biochemical programs that allow inflamed tissues to regain equilibrium. In this review, we spotlight the resolution to inflammation as a strategy to prevent tissue fibrosis and hinder the organ damage.KEYWORDS: inflammation, resolution, fibrosis, wound healing, specialized pro-resolving mediators

BACKGROUND: Statins have been used for around three decades as the primary way to lower cholesterol and reduce the risk of atherosclerosis, but in some groups, statin resistance is common, and the danger of atherosclerosis is still high.CONTENT: Atherosclerosis was once believed to be caused by cholesterol and thrombotic material passively accumulating in the walls of arteries. However, current knowledge shows that the immune cells and inflammatory processes are essential in the formation, progression, and consequences of atherosclerotic lesions, characterized by a persistent inflammatory response, including thrombotic complications. Study of genetic, creating risk score for atherosclerosis, add more information to create more new therapies targeting low density lipoprotein cholesterol (LDL-C) receptor, and shows prospect.SUMMARY: Over time, atherosclerosis theories and treatment strategies have changed. While statins were widely used, they have now been supplanted by alternative options like the proprotein convertase subtilisin/kexin type 9 (PSCK9) inhibitor that manage atherosclerosis more effectively and comprehensive.KEYWORDS: atherosclerosis, cholesterol, inflammation, immune system, metabolism

BACKGROUND: Dendritic cell (DC)-based cancer therapy is a promising adjuvant therapy for nasopharyngeal cancer (NPC) after chemoradiation. Owing to low immunity after chemoradiation, DC therapy activates immune responses. Moreover, DC-based cancer therapy can decrease tumor progression, prolong lifespan, and increase the quality of life of patients. Various studies regarding the use of DC therapy for NPC have been reported, however there are limited reviews on the implementation and foundation of DC immunotherapy to expand this technology.METHODS: A literature search was performed on EMBASE, ScienceDirect, PubMed (MEDLINE), and Cochrane Library, with the term dendritic cells therapy for nasopharyngeal cancer, dendritic cell immunotherapy in nasopharyngeal cancer patients, and DC therapy in NPC, as the search keywords.RESULTS: A total of 199 literatures were reviewed, and four clinical trials were identified as relevant for this review. DC vaccines can be processed with various maturation and activation processes. Selected literatures reported antigens used when incubating the DC are latent membrane protein (LMP) 1, LMP2, and Epstein–Barr virus nuclear antigen 1 (EBNA1). Although DC therapy was produced from different pathways, it has been reported that there are increases of cluster of differentiation (CD)8+ T cells, CD4+ T cells, and the progression free survival (PFS) rate in DC immunotherapy patients than the radiochemotherapy patients.CONCLUSION: It can be concluded that DC could be used as an adjuvant therapy alongside the standard therapy of NPC, which prolongs NPC patient survival.KEYWORDS: adjuvant cell therapy, nasopharyngeal cancer therapy, dendritic cells
