Caffeine activates HOG-signalling and inhibits pseudohyphal growth in Saccharomyces cerevisiae

open access: yesBMC Research Notes, 2023
Objective Caffeine has a wide range of effects in humans and other organisms. Caffeine activates p38 MAPK, the human homolog to the Hog1 protein that orchestrates the high-osmolarity glycerol (HOG) response to osmotic stress in the yeast Saccharomyces ...

The Taste of Caffeine [PDF]

open access: yesJournal of Caffeine Research, 2017
Many people avidly consume foods and drinks containing caffeine, despite its bitter taste. Here, we review what is known about caffeine as a bitter taste stimulus. Topics include caffeine's action on the canonical bitter taste receptor pathway and caffeine's action on noncanonical receptor-dependent and -independent pathways in taste cells.

Cerebral blood flow and behavioural effects of caffeine in habitual and non-habitual consumers of caffeine: A near infrared spectroscopy study [PDF]

open access: yes, 2011
Caffeine has been shown to modulate cerebral blood flow, with little evidence of tolerance to these effects following habitual use. However, previous studies have focused on caffeine levels much higher than those found in dietary servings and have ...
