The architecture of cell differentiation in choanoflagellates and sponge choanocytes

The architecture of cell differentiation in choanoflagellates and sponge choanocytes SUMMARY: The closest relative to multicellular animals are single-celled organisms called choanoflagellates. These protists look like collar cells. These are cells that have a microvillar ring (the collar) around a flagellum. An example of these cells in animals are sensory epidermal cells. To get a… Continue reading The architecture of cell differentiation in choanoflagellates and sponge choanocytes

The Endocannabinoid System of Animals

The Endocannabinoid System of Animals SUMMARY: This article talks about the endocannabinoid system (ECS) in animals. The first and second section talk about the three parts of the ECS: receptors (CBR1 and CBR2), ligands (endocannabinoids), and the ligand degrading enzymes. The receptors are G-protein coupled receptors, the ligands bind directly to these receptors, and the… Continue reading The Endocannabinoid System of Animals

Genetic diversity of Entamoeba in cockroaches

Genetic diversity of Entamoeba: Novel ribosomal lineages from cockroaches SUMMARY: Researchers in this study looked at the diversity of Entamoeba in 3 different species of cockroaches (the American roach, the Dubia roach, and the Madagascar hissing roach) by looking at SSU rDNA in the ground up intestines of the cockroaches. They found that the Entamoebas… Continue reading Genetic diversity of Entamoeba in cockroaches

Relationship between the flagellates and the ciliates

Relationship between the flagellates and the ciliates SUMMARY: This is an article comparing the structural and genomic differences between ciliates and flagellates. Dinoflagellates seem to be the ancestors of ciliates based on similarities in various cell structures and rRNA sequencing. Structures compared in this article include: mitochondria, mechanisms of cilia and flagella, nucleus, and how… Continue reading Relationship between the flagellates and the ciliates
