The characterization of the cellular and molecular mechanisms that mediate inflammation provides a foundation that supports future studies that will de fine mechanisms more intimately. It encourages substantial optimism about the opportunities to understand the inflammatory process and to use that information to develop novel therapeutic approaches. Recent progress has defined the cells that mediate the inflammatory response, many of the inter cellular transmitters, the receptors, signal transduction processes and regula tory mechanisms. Thus, we now have the opportunity to understand...

The NATO Advanced Studies Institute series "Targeting of Drugs" was originated in 1981. It is now a major international forum, held every two years in Cape Sounion, Greece, in which the present and the future of this important area of research in drug carriers is discussed in great depth. Four previous ASls of the series dealt with drug carriers of natural and synthetic origin, their interaction with the biological milieu and with ways by which the latter influences such interaction. The present book contains the proceedings of the 5th NATO ASI "Targeting of Drugs: Optimization Strategies"...

The heat-shock proteins in E. coli are transiently overexpressed af ter shift to a higher growth temperature. The genes that encode the HSPs are preceded by promoters transcribed in vitro by a form of RNA poly 32 32 merase holoenzyme containing a 32-kd a subunit (Ea ). The a subunit is encoded by the rpoH (htpR) gene, previously identified as a positive 32 effector of the heat-shock response. Our evidence suggests that Ea is the enzyme that transcribes heat-shock genes at all temperatures. The level 32 of a may be regulated at several points: Accumulation of rpoH mRNA 32 is affected by...
