Non-human primate (NHP) Core

点击翻译按钮获取中文摘要

The Pathology Core has a unique team of investigators with the professional expertise to assist with the design and implementation of the unique vaccine strategies proposed. The Core Director, Dr. Altman, is a veterinary pathologist and laboratory animal veterinarian. He will coordinate tissue collection, presevation, sample preparation, and distribution. Additional, he will assist in the intrepatation of tissue changes and biomarkers. The Co-Director, Dr. Nadji, is a surgical pathologist with expertise in diagnostic and predictive biomarkers. He has developed unique procedures which will be extremely important in identifing the molecular and cellular mechanisms involved in the immune responses. The techniques proposed including immunohistochemistry and in situ hybridization are highly sensitive in identification of cellular changes. The procedures utilized will preserve macromolecules in tissue traditionally achieved by immediate freezing. The Research lnvestigator, Dr. Datar, is the Co-Director of the UM Biomedical Nanotechnology Institute and an experienced molecular biologist with many years of experience in gene expression analysis of fresh and archival tissues. He will lead the Laser Capture Microdissection procedues which are critical to the research projects in this proposal. Lay Summary: This project is targeted to use two novel vaccine strategies in a Rhesus monkey model of SIV infection to understand the molecular and cellular mechanisms that provide protection against this disease. State-of-the art-techniques and procedures will be utilized to characterize changes at critical time points after infection. The information obtained will help to develop an effective HIV vaccine for humans.
