Autophagic flux is required for the synthesis of triacylglycerols and ribosomal protein turnover in Chlamydomonas [PDF]

open access: yes, 2018
Autophagy is an intracellular catabolic process that allows cells to recycle unneeded or damaged material to maintain cellular homeostasis. This highly dynamic process is characterized by the formation of double-membrane vesicles called autophagosomes ...

Differential Effects of Iron, Zinc, and Copper on Dictyostelium discoideum Cell Growth and Resistance to Legionella pneumophila

open access: yesFrontiers in Cellular and Infection Microbiology, 2018
Iron, zinc, and copper play fundamental roles in eucaryotes and procaryotes, and their bioavailability regulates host-pathogen interactions. For intracellular pathogens, the source of metals is the cytoplasm of the host, which in turn manipulates ...

Systemic infection of freshwater crayfish Cherax quadricarinatus by hymenostome ciliates of the Tetrahymena pyriformis complex [PDF]

open access: yes, 1996
A survey of cultured freshwater crayfish Cherax quadricarinatus in north Queensland revealed systemic infections by hymenostome ciliates in moribund crayfish from one location. The ciliates were identified following protargol impregnation as belonging to

Copine A Interacts with Actin Filaments and Plays a Role in Chemotaxis and Adhesion

open access: yesCells, 2019
Copines make up a family of calcium-dependent, phospholipid-binding proteins found in numerous eukaryotic organisms. Copine proteins consist of two C2 domains at the N-terminus followed by an A domain similar to the von Willebrand A domain found in ...

Potassium channel KCN11 is required for maintaining cellular osmolarity during nitrogen starvation to control proper cell physiology and TAG accumulation in Chlamydomonas reinhardtii

open access: yesBiotechnology for Biofuels, 2020
Background Nitrogen (N) starvation in algae induces a variety of structural and metabolic changes including accumulation of triacylglycerol (TAG). Given the promising prospect of using algae as feedstock for biofuel production, accumulation of TAG upon N
