The Gerontological Society of America (GSA) will be hosting the World Congress of Gerontology and Geriatrics, where they will welcome the global community of aging scholars. GSA will be hosting this event in San Francisco from July 23rd to the 27th on behalf of the International Association of Gerontology and Geriatrics (IAGG). The GSA Annual Scientific Meeting, normally held each November, will not take place this year. However, the GSA will be implementing many of the Society’s traditional meeting activities in a modified fashion during the World Congress. For more details please visit www.iagg2017.org.
The Geropathology Grading Committee has published its first description of the Geropathology Grading Platform in the Journals of Gerontology: Biological Sciences.

Testing drugs for anti-aging effects has historically been conducted in mouse life-span studies, but are costly and time consuming, and more importantly, difficult to recapitulate in humans. In addition, life-span studies in mice are not well suited to testing drug combinations that target multiple factors involved in aging. Additional paradigms for testing therapeutics aimed at slowing aging are needed. A new paradigm, designated as the Geropathology Grading Platform (GGP), is based on a standardized set of guidelines developed to detect the presence or absence of low-impact histopathological lesions and to determine the level of severity of high-impact lesions in organs from aged mice. The GGP generates a numerical score for each age-related lesion in an organ, summed for total lesions, and averaged over multiple mice to obtain a composite lesion score (CLS). Preliminary studies show that the platform generates CLSs that increase with the age of mice in an organ-dependent !
manner. The CLSs are sensitive enough to detect changes elicited by interventions that extend mouse life span, and thus help validate the GGP as a novel tool to measure biological aging. While currently optimized for mice, the GGP could be adapted to any preclinical animal model.

On January 23rd and 24th, 2017, the Geropathology Grading Committee held a workshop which succeeded with its main goal of upgrading and expanding its Geropathology Grading Platform by evaluating and comparing lesion grades in specific organs and tissues from mice at various ages and drug testing regimes. A summary of the 2017 Geropathology Grading Committee Workshop can be found here.
