He continued his studies of the zoospores and male cells of Algae and other similar plants, and contributed to the understanding of such motile stages in vegetable life.
Propionibacterium freudenreichii is a Gram-positive, non-motile bacterium that plays an important role in the creation of Emmental cheese, and to some extent, Leerdammer.
NO signalling has also been shown to control the motility of endothelial cells by regulating the expression of cell adhesion molecules ICAM-1.
Australian research conducted in 2009 by subjecting in vitro samples of human spermatozoa to radio-frequency radiation at 1.8 GHz and specific absorption rates (SAR) of 0.4 to 27.5 W/kg showed a correlation between increasing SAR and decreased motility and vitality in sperm, increased oxidative stress and 8-Oxo-2'-deoxyguanosine markers, stimulating DNA base adduct formation and increased DNA fragmentation.
Indeed NFAT3 (NFATc4) is an inhibitor of cell motility by blocking the expression of LCN2.
In some mammals, sperm motility is activated by increase in pH, calcium ion and cAMP, yet it is suppressed by low pH in the epididymis.
