X-Message-Number: 20990 From: Date: Tue, 28 Jan 2003 09:59:00 EST Subject: HSP --part1_9f.32dee7b5.2b67f4b4_boundary Content-Type: text/plain; charset="US-ASCII" Content-Transfer-Encoding: 7bit There are both Heat shock protein complexes (HSP) and cold shock protein compexes(CSP). Yvan made a good point at how important these complexes are and a novel mechanism for augmentation. Interestingly humans have the abiliy to make several of bot HSP and CSP's. When exposed to high body temps (45C) for a brief time we augment the production of HSP's. Brief immersion in water below (6C) does the same for CSP's. Many plants, nematodes, and microbes survive repetative freezing by use of CSP's. Realisticly humans can't produce anywhere near the concentration necessary for complete cyroprotection, but wouldn't it be productive to augment the production of CSP's prior to cyropreservation? It would be positive from a pro-longevity standpoint.
