A large focus was on aging and neurodegeneration including a number of presentations on Alzheimer’s disease. Other topics included cardiomyopathy, frailty, metabolism, pharmaceutical intervention of aging, age-related epigenetic modification, and cancer and aging. This annual meeting is well-attended and provides a seclusive and rustic environment in the Texas Hill Country for small group presentations and extensive informal interactions and discussions on the very latest findings and current thinking in the causes and prevention of aging and age-related diseases. LDLR-related protein 1 increases cytokine sensitivity. Implications for recovery after brain damage Sadiya Ahmad, Pamela Reed, Shane Sprague, Naomi L. Sayre University of Texas Health Science Center at San Antonio (UTHSCSA), TX Patients that express the Apolipoprotein E4 are predisposed to a poor long-term outcome after stroke. Explanations for this increased risk are not yet elucidated. This study aims to test one possible mechanism by which ApoE4 contributes to cognitive decline after stroke. Here, we examine the effect of a major ApoE4 receptor, low-density lipoprotein receptor related protein 1 (LRP1) on sensitivity to stress in astrocytes. LRP1 can promiscuously bind and move several extracellular ligands and plasma membrane proteins into the endocytic system. Notably, LRP1 was previously found to remove the TNF receptor (TNFR1) from the plasma membrane, although this has not been shown in astrocytes. We propose that a similar mechanism occurs in the central nervous system to attenuate inflammatory response after stroke. LRP1 binds and clears ApoE4 from the extracellular space via receptor-mediated endocytosis. However, previous studies have shown that the ApoE4, compared to other ApoE isoforms, slows the trafficking and recycling of endocytic LDL receptors. We propose that ApoE4 similarly inhibits LRP1 trafficking, and hypothesize that ApoE4 inhibits the ability of LRP1 to remove TNFR1 from the plasma membrane. This is expected to increase cytokine sensitivity, which would result in worse outcome after stroke and with aging. We investigated the effect of LRP1 on astrocyte TNFα signaling and response in immortalized ApoE null mouse astrocytes subjected to lentiviral-mediated knockdown ofLRP1. The astrocyte response to TNFα stimulation was tested in a concentration dependent manner using Western blotting of NFkB pathway components, which are the downstream mediators of TNFα signaling. We also tested astrocyte viability after prolonged TNFα stimulation using Alamar Blue reagent. We found that LRP1 deficient cells have increased phosphorylation of NFkB upon TNFα stimulation, and that loss of LRP1 resulted in significant loss of astrocyte viability after prolonged stimulation. Altogether, our results indicate that loss of LRP1 renders astrocytes more sensitive to TNFα.

Exendin-4 is an United States Food and Drug Administration (FDA) approved glucagon-like peptide that increases insulin dependent glycogen synthesis and glucose uptake. Male NMRI mice (20-25 g), 3 months of age, were randomly divided into 6 groups of 12 mice each: control, exendin-4 (1 nmol/kg), exendin-4 (10 nmol/kg), D-galactose, D-galactose + exendin-4 (1 nmol/kg) and D-galactose + exendin-4 (10 nmol/kg). D-galactose (500 mg/kg) was given daily by oral gavage for 6 weeks. During the last 10 days, exendin-4 (1 and 10 nmol/kg) was injected intraperitoneally daily. Glucose, insulin, insulin resistance, lipid profiles, and hepatic enzyme levels significantly increased in the D-galactose group (<i>p</i> < 0.05), along with a significant decrease in superoxide dismutase activity and pancreatic islet insulin secretion (<i>p</i> < 0.05). Exendin-4 decreased D-galactose-induced increases in serum glucose and insulin, insulin resistance, lipid profiles, and hepatic enzymes, and improved pancreatic islet insulin secretion and antioxidant defense status.

A number of molecular pathways are well known for influencing aging, but only a few have been successfully targeted with individual drugs, and these drugs do not individually target all aging pathways. However, combinations of these drugs might have the potential of effectively broadening the scope of aging targets. There are a number of drug combinations that could be combined based on different but overlapping pharmacological activities. Since the number one criterion for selecting drugs should be based on known anti-aging effects, for example, in preclinical mouse studies, the number of drugs available to consider is markedly reduced. Three drugs with well-validated anti-aging effects in laboratory animals, rapamycin [2,3], acarbose [4], and SS31 [5,6], are well suited to therapeutic multiplexing as a way to enhance healthy aging and stop the development of lesions associated with aging and physiological dysfunction based on interactive cellular mechanisms of each drug. The inter-drug relationship of these three drugs can easily be perceived by explicitly defining the mechanism of action of each drug and how it overlaps and extends the mechanism of action of each of the other drugs in the complex.

By definition, resilience decreases with increasing age, while frailty, defined as a decline in tissue function, increases with increasing age. Assessment of resilience could therefore be an informative early paradigm to predict healthy aging compared to frailty, which measures late life dysfunction. Parameters for resilience in the laboratory mouse are not yet well defined, and no single standardized stress test exists. Since aging involves multiple genetic pathways, integrative responses involving multiple tissues, organs, and activities need to be measured to reveal the overall resilience status, suggesting a battery of stress tests, rather than a single all-encompassing one, would be most informative. Three simple, reliable, and inexpensive stressors are described in this review that could be used as a panel to determine levels of resilience. Brief cold water immersion allows a recovery time to normothermia as an indicator of resilience to hypothermia, i.e. the quicker the return to normal body temperature, the more robust the resilience. Sleep deprivation (SD) impairs remote memory in aged mice, and has detrimental effects on glucose metabolism. Cyclophosphamide (CYP) targets white blood cells, especially myeloid cells resulting in neutropenia with a rebound neutrophilia in an age-dependent manner. Thus a strong neutrophilic response indicates resilience. In conclusion, resilience promises to be an especially useful measurement of biological age, i.e. how fast a particular organ or tissue ages. The three stressors, cold, SD, and CYP, are applicable to human medicine and aging because they represent clinically relevant stress conditions that have effects in an age-dependent manner. They are thus an attractive perturbation for resilience testing in mice to measure the effectiveness of interventions that target basic aging processes.</p>","PeriodicalId":89611,"journal":{"name":"Pathobiology of aging & age related diseases","volume":"8 1","pages":"1403844"},"PeriodicalIF":0.0,"publicationDate":"2017-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/20010001.2017.1403844","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"35699687","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Within the Anatomic Pathology Working Group, a Geropathology Grading Committee was formed for the purpose of developing guidelines for a scoring system based on the increasing severity of lesions associated with increasing age, using the mouse as the preclinical prototype model. The committee consists of a chair, Warren Ladiges, DVM, MSc, a program coordinator, John Morton, BS, from the Department of Comparative Medicine, University of Washington, Seattle, WA, and six boardcertified veterinary pathologists: Denny Liggitt, DVM, PhD and Jessica Snyder, DVM, PhD, from the Department of Comparative Medicine, University of Washington, Seattle, WA, Tim Snider, DVM, PhD, from the Department of Veterinary Pathology, Oklahoma State University, Stillwater, OK, Erby Wilkinson, DVM, PhD, from the Department of Pathology, University of Michigan, Ann Arbor, MI, Denise Imai, DVM, PhD, from the Department of Comparative Pathology, University of California, Davis, Davis, CA, and Smitha Pillai, DVM, PhD, from the Fred Hutchinson Cancer Research Center, Seattle, WA. This committee has been actively engaged in teleconferences, meetings, and workshops to develop the Geropathology Grading Platform (GGP). The GGP is based on a standard set of guidelines designed to (1) detect the histological presence or absence of lowimpact lesions; and (2) determine the level of severity of high-impact lesions in organs from aged mice [1]. The platform is designed to generate a numerical score for each lesion in a specific organ, so that a total lesion score is obtained by adding each lesion score for that organ for one mouse. Total lesion scores are averaged between all mice in a specific cohort to obtain a composite lesion score (CLS) for that organ. The CLS can then be used to compare responses to drug treatment over time, determine the effect of alterations in gene expression, or investigate the impact of environmental challenges in a variety of preclinical aging studies [2]. This platform has been used to compare CLS in two different mouse strains at increasing ages, showing that CLSs increase similarly in both strains with increasing age but at different rates in different organs [3].
