The present results strongly suggest that previous activation of 5-HT1A receptors or antagonism of 5-HT2A receptors protects against heatstroke by reducing circulatory shock and cerebral ischemia, whereas prior antagonism of 5-HT1A receptors or activation of 5-HT2A receptors exacerbates heatstroke.
