Animal Physiology > Signal Transduction > Topic 2: Intracellular Signal Transduction

(3 of 3)

Why do we know so much about this olfactory signal transduction pathway? Because female mosquitoes that are carriers of diseases like malaria and sleeping sickness use this same pathway - it has been the subject of a great deal of research.

Compared to their female counterparts, male mosquitoes are benign vegetarian monks who feed on plant juices. In fact, the male mosquito does not respond to lactic acid from human sweat. From your knowledge of signal transduction, why do you think males cannot respond to lactic acid?



In the third and final topic, you will see how malfunctioning of a signal transduction pathway can lead to disease.
