Abstract

BACKGROUND: Obesity has been decades become a highly interest study, accompanied by the realization that adipose tissue (AT) plays a major role in the regulation of metabolic function.CONTENT: In past few years, adipocytes classification, development, and differentiation has been significant changes. The white adipose tissue (WAT) can transform to a phenotype like brown adipose (BAT) type and function. Exercise and cold induction were the most common factor for fat browning; however batokines such as fibroblast growth factor (FGF)-21, interleukin (IL)-6, Slit homolog 2 protein (SLIT2)-C, and Meteorin-like protein (METRNL) perform a beneficial browning action by increasing peroxisome proliferator-activated receptor gamma coactivator (PGC)-1α protein levels, a key factor to stimulate mitochondrial biogenesis and uncoupling Protein 1 (UCP1) transcription, thus change the WAT phenotype into beige.SUMMARY: AT recently known as a complex organ, not only bearing a storage function but as well as the master regulator of energy balance and nutritional homeostasis; brown and beige fat express constitutively high levels of thermogenic genes and raise our expectation on new strategies for fighting obesity and metabolic disorders.KEYWORDS: obesity, white adipose tissue, brown adipose tissue, beige adipose tissue, inflammation, IR, metabolic disease

Abstract

BACKGROUND: Most medical treatments have been designed for the “average patients”. As a result of this “one-size-fits-all-approach”, treatments can be very successful for some patients but not for others. The issue is shifting by the new innovation approach in diseases treatment and prevention, precision medicine, which takes into account individual differences in people’s genes, environments, and lifestyles. This review was aimed to describe a new approach of healthcare performance strategy based on individual genetic variants.CONTENT: Researchers have discovered hundreds of genes that harbor variations contributing to human illness, identified genetic variability in patients’ responses to different of treatments, and from there begun to target the genes as molecular causes of diseases. In addition, scientists are developing and using diagnostic tests based on genetics or other molecular mechanisms to better predict patients’ responses to targeted therapy.SUMMARY: Personalized medicine seeks to use advances in knowledge about genetic factors and biological mechanisms of disease coupled with unique considerations of an individual’s patient care needs to make health care more safe and effective. As a result of these contributions to improvement in the quality of care, personalized medicine represents a key strategy of healthcare reform.KEYWORDS: precision medicine, genomic, proteomic, metabolomic

Abstract

BACKGROUND: Current understanding in molecular character of natural killer (NK) cell, its function and mechanisms, send people the ideas to develop a NK cell-based immunotherapeutic strategies against human cancer.CONTENT: Before being regards as a cell-based cellular therapy, NK cell have to be clinical proven. Early studies with NK cells infusions for acute myeloid leukemia and lung cancer showed a promising result. NK cells need simplified methods for enriching and expanding, in addition to its transfection with chimeric antigen receptors (CARs). NK-92 arise as an assuring effector cells to augment monoclonal and bispecific antibody therapy. Thus, NK cells show a potential opportunity for cell engineering, outstep the era of T cells.SUMMARY: It is believed that NK cells bring a bright hope for future cancer immunotherapies, either alone or in combination as a harmonious therapy.KEYWORDS: NK cells, NK-92 cells, immunotherapy, CAR

Abstract

BACKGROUND: Over the past 50 years, scientists have recognized that not all adipose tissue is alike, and that health risk is associated with the location as well as the amount of body fat. Different depots are sufficiently distinct with respect to fatty-acid storage and release as to probably play unique roles in human physiology. Whether fat redistribution causes metabolic disease or whether it is a marker of underlying processes that are primarily responsible is an open question.CONTENT: The limited expandability of the subcutaneous adipose tissue leads to inappropriate adipose cell expansion (hypertrophic obesity) with local inflammation and a dysregulated and insulin-resistant adipose tissue. The inability to store excess fat in the subcutaneous adipose tissue is a likely key mechanism for promoting ectopic fat accumulation in tissues and areas where fat can be stored, including the intra-abdominal and visceral areas, in the liver, epi/pericardial area, around vessels, in the myocardium, and in the skeletal muscles. Many studies have implicated ectopic fat accumulation and the associated lipotoxicity as the major determinant of the metabolic complications of obesity driving systemic insulin resistance, inflammation, hepatic glucose production, and dyslipidemia.SUMMARY: In summary, hypertrophic obesity is due to an impaired ability to recruit and differentiate available adipose precursor cells in the subcutaneous adipose tissue. Thus, the subcutaneous adipose tissue may be particular in its limited ability in certain individuals to undergo adipogenesis during weight increase. Inability to promote subcutaneous adipogenesis under periods of affluence would favor lipid overlow and ectopic fat accumulation with negative metabolic consequences.KEYWORDS: obesity, adipogenesis, subcutaneous adipose tissue, visceral adipose tissue, adipocyte dysfunction

Abstract

BACKGROUND: Hypothalamus is the master regulator of body’s systemic homeostasis including energy balance, body temperature, sleep, blood pressure, and circadian rhythms. This review article will highlight the shifting of the old paradigm of obesityinflammation-metabolic syndrome, which was focused on visceral organs and systemic inflammation, into a new model involving microinflammation in the master regulator of endocrine system, i.e., hypothalamus.CONTENT: Since the early stage of over-nutritional conditions and aging process, microinflammation in hypothalamus has started to emerge, due to the activation of several proinflammatory signaling pathways, especially the nuclear factor kappa B (NF-kB) and c-Jun N-terminal kinase (JNK)-mediated nuclear transcriptional programs. Together with intracellular organelle stress signals, these pathways develop a chronic microinflammatory environment in the hypothalamus leading to obesity and metabolic disorders.SUMMARY: Hypothalamic inflammation has been noted not only as an important driver of impaired energy balance, but also contribute in altered neurocircuit functions and promote obesity-associated metabolic impairment.KEYWORDS: hypothalamus, inflammation, metabolism, obesity, metabolic syndrome

Abstract

BACKGROUND: As population demographic shift and the number of individuals with Alzheimer Disease (AD) continue to increase, the challenge is to develop targeted, effective treatments and our ability to recognize early symptoms. In view of this, the need for specific AD biomarker is crucial.CONTENT: In recent years it has become evident that CSF concentrations of some brain-specific proteins are related to underlying disease pathogenesis and may therefore aid clinical investigation. Among several, we have focused on three candidates that have been suggested to fulfil the requirements for biomarkers of AD: β-amyloid 42 (Aβ42), total Tau (T-tau) and tau phosphorylated at various epitopes (P-tau). An increasing number of studies suggest that supplementary use of these CSF markers, preferably in combination, adds to the accuracy of an AD diagnosis. More recently visinin – like protein (VLP-1), a marker for neuronal cell injury has been studied. CSF VLP-1 concentrations were 50% higher in AD patients than in the control population.SUMMARY: The number of studies aimed at the identification of new biomarkers for AD is expected to increase rapidly, not only because of the increasing insights into the pathological mechanisms underlying this disease, but also because new therapies have been developed or are under consideration now, which warrant an early and specific diagnosis for effective treatment of the patients.KEYWORDS: dementia, amyloid plaque, neurofibrillary tangels, amyloid β-peptide 42 (Aβ42), total tau (T-tau), phosphorylated tau (P-tau), visinin–like protein 1 (VLP-1)

Abstract

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

Abstract

BACKGROUND: Obesity is closely related to chronic, low grade systemic inflammation (metaflammation) and it leads to further metabolic complications such as hypertension, atherosclerosis, and type 2 diabetes due to the adipocytokine imbalance. This study was carried out to assess the correlation between progranulin, granulin, adiponectin and visceral adipose tissue-derived serine protease inhibitor (Vaspin) with metaflammation (high sensitivity C-reactive protein (hs-CRP)) in centrally obese men.METHODS: This study was observational with a cross sectional design involving 60 men aged 30-60 years, consisted of 43 obese men (waist circumference (WC) ≥90 cm) and 13 non obese men (WC <90 cm), with no hypertension, and no renal dysfunction. Anthropometric parameters, creatinine, serum glutamic oxaloacetic transferase (SGOT), serum glutamic piruvic transferase (SGPT) and hs-CRP levels were measured. Serum concentrations of progranulin, granulin, adiponectin and Vaspin were measured by ELISA.RESULTS: This study showed in obese men a significant correlation between hs-CRP and Vaspin (r=0.305; p=0.046), non-significant correlation between hs-CRP and progranulin (r=0.048; p=0.758), between hs-CRP and granulin (r=-0.223; p=0.150), also between hs-CRP and adiponectin (r=-0.121; p=0.439). Similar patterns were observed between adipokines level and WC. There were 3 patterns showing increase or decrease of adipokines value with WC between 80-86 cm; subsequently the pattern tended to become flat with WC between 86-105 cm, then showing increase or decrease of adipokines value with WC >105 cm.CONCLUSION: We found metaflammation (hs-CRP) was significantly correlated with Vaspin, but not with progranulin, granulin and adiponectin, in obese men. We suggest the possibility of a dynamic expression of adipokines related to WC that are subjected to adipocytes hypertrophy-hyperplasia phenomenon.KEYWORDS: progranulin, granulin, adiponectin, Vaspin, hs-CRP, metaflammation, central obesity

Abstract

BACKGROUND: Current cancer drugs and treatments are aiming at eradicating tumor cells, but often are more toxic then effective, killing also the normal cells and not selectively the tumor cells. There is good personalized cancer therapy that involves administration to the cancer-bearing host of immune cells with direct anticancer activity, which called adoptive cell therapy (ACT). A review of the unique biology of T cell therapy and of recent clinical experience compels a reassessment of target antigens that traditionally have been viewed from the perspective of weaker immunotherapeutic modalities.CONTENT: Chimeric antigen receptors (CAR) are recombinant receptors which provide both antigen-binding and T cell-activating functions. Many kind of CARs has been reported for the past few years, targeting an array of cell surface tumor antigens. Their biologic functions have extremely changed following the introduction of tripartite receptors comprising a costimulatory domain, termed second-generation CARs. The combination of CARs with costimulatory ligands, chimeric costimulatory receptors, or cytokines can be done to further enhance T cell potency, specificity and safety. CARs reflects a new class of drugs with exciting potential for cancer immunotherapy.SUMMARY: CAR-T cells have been arising as a new modality for cancer immunotherapy because of their potent efficacy against terminal cancers. They are known to exert higher efficacy than monoclonal antibodies and antibodydrug conjugates, and act via mechanisms distinct from T cell receptor-engineered T cells. These cells are constructed by transducing genes encoding fusion proteins of cancer antigen-recognizing single-chain Fv linked to intracellular signaling domains of T cell receptors.KEYWORDS: chimeric antigen receptor, CAR-T cells, adoptive cell therapy, ACT, T cell receptor, TCR, cancer, immunotherapy

Abstract

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
