Do Cellular Heat Acclimation Responses Modulate Central Thermoregulatory Activity?

The classical concept of heat acclimation is of an autonomically controlled array of integrative physiological processes, improving heat tolerance. New evidence suggests that a temporal interplay between opposing autonomic and peripheral cell-originated responses, switched on by heat and autonomic stimulation of the cell membrane, and a marked increase in the stock of the inducible 70-kDa heat shock protein contribute to widening of the thermoregulatory activity span.
