However, using an optogenetic inhibition of different populations of interneurons, it was recently demonstrated that silencing SRIF interneurons increases burst firing of pyramidal cells without altering the theta phase of spikes (Royer et al., 2012)

In this article, the authors showed that uPAR is expressed in senescence cells, both in in vivo and in vitro models (liver fibrosis, pancreatic intraepithelial neoplasia, senescent melanocytes, or lung cancer) correlated to a lack of expression in healthy tissue, except for the bronchial epithelium and a subset of immune cells in which a weak expression of uPAR was detected
Disclosure to sunlight will indirectly affect the whitening process since it enhances the melanin pigments to the skin, thus, it might delay the whitening process
