Cilia are ubiquitous and highly conserved extension that endow the cell with motility and
sensory functions. They were present in the first eukaryotes and conserved throughout …

In ciliates, a variety of processes are regulated by Ca2+, eg, exocytosis, endocytosis, ciliary
beat, cell contraction, and nuclear migration. Differential microdomain regulation may occur …

Unicellular organisms use gravity as an environmental guide to reach and stay in regions
optimal for their growth and reproduction. These single cells play a significant role in food …

Holotrichous ciliates, like Paramecium, swim through their aqueous environment by beating
their many cilia. They can alter swimming speed and direction, which seems to have …

Making progress in the study of hormone‐sensitive signaling systems in vertebrates and
human requires a better understanding of how chemosignaling systems in lower eukaryotes …

Previously, we have shown that ethanol (EtOH) stimulates a rapid increase in the ciliary beat
frequency (CBF) of bovine bronchial epithelial cells (BBECs) via the activation of PKA. We …

Cilia are highly conserved for their structure and also for their sensory functions. They serve
as antennae for extracellular information. Whether the cilia are motile or not, they respond to …

Channels, pumps, receptors, cyclases and other membrane proteins modulate the motility
and sensory function of cilia, but these proteins are generally under-represented in …

Protozoa are eukaryotic cells and represent suitable model systems to study the
mechanisms of gravity perception and signal transduction due to their clear gravity‐induced …

Guanylyl cyclases in eukaryotic unicells were biochemically investigated in the ciliates
Paramecium and Tetrahymena, in the malaria parasite Plasmodium and in the ameboid …
