Abstract

T-type Ca channels are widely expressed throughout the urinary and male genital tracts, generally alongside L-type Ca channels. The use of pharmacological blockers of these channels has suggested functional roles in all regions, with the possible exception of the ureter. Their functional expression is apparent not just in smooth muscle cells but also in interstitial cells that lie in close proximity to muscle, nerve and epithelial components of these tissues. Thus, T-type Ca channels can contribute directly to modulation of muscle function and indirectly to changes of epithelial and nerve function. T-type Ca channel activity modulates phasic contractile activity, especially in conjunction with Ca -activated K channels, and also to agonist-dependent responses in different tissues. Upregulation of channel density occurs in pathological conditions associated with enhanced contractile responses, e.g. overactive bladder, but it is unclear if this is causal or a response to the pathological state. Moreover, T-type Ca channels may have a role in the development of prostate tumours regulating the secretion of mitogens from neuroendocrine cells. Although a number of selective channel blockers exist, their relative selectivity over L-type Ca channels is often low and makes evaluation of T-type Ca channel function in the whole organism difficult. © 2014 Springer-Verlag.
