The architecture of cell differentiation in choanoflagellates and sponge choanocytes

GwynneL.

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

Using Phytochemicals to Inhibit Efflux Pumps in Bacteria

GwynneL.

Inhibiting Bacterial Drug Efflux Pumps via Phyto-Therapeutics to Combat Threatening Antimicrobial Resistance SUMMARY: Many plants produce chemicals that kill bacteria or prevent their growth. This article looks at how the plant chemicals affect efflux pumps. The first and second sections explain what efflux pumps are and describes the many roles they play in bacteria cells,… Continue reading Using Phytochemicals to Inhibit Efflux Pumps in Bacteria

All About Efflux Pumps

GwynneL.

Bacterial Multidrug Efflux Pumps: Much More Than Antibiotic Resistance Determinants SUMMARY: Efflux pumps are found in all organisms; they play an important role in helping the cells pump out toxins, heavy metals, and in the case of antibiotic resistant bacteria, antibiotics! This article talks about how efflux pumps work, other ways that they are used… Continue reading All About Efflux Pumps
