WebMembrane ion channels of the calcium homeostasis modulator (CALHM) family promote cell–cell crosstalk at neuronal synapses via ATP release, where ATP acts as a neurotransmitter. CALHM6, the only CALHM highly expressed in immune cells, has been linked to the induction of natural killer (NK) cell anti-tumour activity. WebSimple diffusion lets small non-polar molecules cross cell membranes, but the fatty acids of these membranes block polar and large molecules. Facilitated diffusion allows blocked molecules essential for cell processes to cross the membranes through membrane-embedded carrier proteins.
