DOI: 10.1098/rsbl.2022.0042
Abstract: The continued emissions of anthropogenic carbon dioxide are causing progressive ocean acidification (OA). While deleterious effects of OA on biological systems are well documented in the growth of calcifying organisms, lesser studied impacts of OA… read more here.

DOI: 10.1371/journal.pcbi.1006109
Abstract: To navigate their surroundings, cells rely on sensory input that is corrupted by noise. In cells performing chemotaxis, such noise arises from the stochastic binding of signalling molecules at low chemoattractant concentrations. We reveal a… read more here.

DOI: 10.1371/journal.pcbi.1008826
Abstract: Sperm of marine invertebrates have to find eggs cells in the ocean. Turbulent flows mix sperm and egg cells up to the millimeter scale; below this, active swimming and chemotaxis become important. Previous work addressed… read more here.

DOI: 10.3390/ijms22179104
Abstract: In echinoderms, sperm swims in random circles and turns in response to a chemoattractant. The chemoattractant evokes transient Ca2+ influx in the sperm flagellum and induces turning behavior. Recently, the molecular mechanisms and biophysical properties… read more here.

DOI: 10.3390/ijms23074069
Abstract: Fertilization requires sperm migration toward oocytes and subsequent fusion. Sperm chemotaxis, a process in which motile sperm are attracted by factors released from oocytes or associated structures, plays a key role in sperm migration to… read more here.

Sperm chemotaxis in marine invertebrates and mammals

DOI: 10.4103/2096-2924.216863
Abstract: Sperm respond to multiple chemical factors derived from the eggs and reorient their migratory direction – a process called chemotaxis. The chemotaxis of sperm in marine invertebrates has been established well. A couple of ion… read more here.
