A phagocytic function assay of canine granulocytes was established. This method allows the proportion of active granulocytes to be estimated as well as the number of adhered and ingested yeast cells. The influence of different factors on phagocytosis was studied. Temperature variation within the interval 36-41 degrees C did not affect phagocytosis. The incubation time for optimal phagocytosis of yeast cells was 35 min. The opsonization procedure giving the optimal phagocytosis was purified IgG and serum together.

Serine-arginine protein kinases (SRPKs) play important roles in diverse biological processes such as alternative splicing and cell cycle. However, the functions of SRPKs in DNA damage response remain unclear. Here we characterized the function of SRPKs homolog Dsk1 in regulating DNA repair in the fission yeast Schizosaccharomyces pombe.

Many protein complexes are highly dynamic in cells; thus, characterizing their conformational changes in cells is crucial for unraveling their functions. Here, using cryo-electron microscopy, 451,700 ribosome particles from Saccharomyces cerevisiae cell lamellae were obtained to solve the 60S region to 2.9-Å resolution by in situ single-particle analysis.

Aureobasidium melanogenum is a black yeast-like fungus that occurs frequently both in nature and in domestic environments. It is becoming increasingly important as an opportunistic pathogen. Nevertheless, its effect on human cells has not yet been studied.

Mitochondrial morphology is a result of regulated opposite events called fission and fusion and requires the GTPase, dynamin-related protein 1 (DRP1/Dnm1), or its homologs. A recent clinical report identified a heterozygous missense mutation in the human DRP1 that replaces Glycine (G) 149 with Arginine (R) and results in debilitating conditions in the patient. In this study, we mimicked this mutation in yeast Dnm1 (G178R) and investigated the impact of the pathogenic mutation on the protein's function.

Aquaporin 1 (AQP1) is a key channel for water transport in peritoneal dialysis. Inhibition of AQP1 could therefore impair water transport during peritoneal dialysis. It is not known whether inhibition of AQP1 occurs unintentionally due to off-target interactions of administered medications.
