RESUMO

The contribution of the researchers of IDR to some early discoveries on endorphins is recounted. Exact determination of the amino acid sequence of beta-lipotropin, discovery of the analgesic action of beta-endorphin in rats, demonstration of the partial cross-tolerance between morphine and beta-endorphin, description of the elevation of the pain threshold upon inhibition of the enzymatic breakdown of endogenous opioids by bacitracin, demonstration of inhibition of opiate tolerance and dependence by alpha-MSH and Met-enkephalin, development of the second strongest enkephalin analogue, D-Met2,Pro5-enkephalinamide, recognition of some factors conferring analgesic activity to synthetic enkephalin analogues, etc. prove that IDR has played an active role in the early history of endorphin research.

RESUMO

This paper and the following four papers summarize a symposium on the role of opioids in regulation of feeding, body weight, and energy expenditure. The central sites of opioid action are discussed, as is opioid activity in invertebrates, large animals, and humans. This paper provides a historical review of developments in the field from the early concepts of an endogenous opioid system to the current understanding of multiple receptor types and their interaction in regulating ingestive behavior. Opioids from all three opioid families may stimulate food intake, and some evidence exists that opioids may stimulate energy expenditure. Eating and drinking behavior is very complex and involves a number of components. Our understanding of the role of opioids in this process is shallow, and future research must be designed carefully to evaluate individual components of ingestive behavior.
