Astrocyte immunometabolic regulation of the tumour microenvironment drives glioblastoma pathogenicity

GwynneL.

https://doi.org/10.1093/brain/awac222 Summary: Glioblastomas are incredibly deadly brain tumors. While there have been decades of research on curing these cancers, survival rates haven't increased much. Recently, a study out of Tel Aviv looked at what makes glioblastomas so resistant to treatment. Results showed that glioblastomas are protected and fed by astrocytes. Astrocytes are specialized glial cells… Continue reading Astrocyte immunometabolic regulation of the tumour microenvironment drives glioblastoma pathogenicity

Using NAC Against Antibiotic Resistance Bacteria

GwynneL.

N-acetyl Cysteine Coated Gallium Particles Demonstrate High Potency against Pseudomonas aeruginosa PAO1 SUMMARY: Antibiotic resistant bacterial infections are on the rise, especially in hospitals. One of the culprits is the bacteria Pseudomonas aeruginosa (POA1). Researchers are quickly running out of antibiotics to use against resistant strains. The problem has reached the point where colistin, a… Continue reading Using NAC Against Antibiotic Resistance Bacteria

Different Enzymes to Digest Different Plant Substrates

GwynneL.

The fungal cultivar of leaf-cutter ants produces specific enzymes in response to different plant substrates SUMMARY: Leaf-cutter ants and a fungus called Leucoagaricus gongylophorus have a symbiotic relationship. The ants harvest plant material for the fungus to “eat” and then the ants feed off of the gongylidia. These swollen parts of the hyphae are no… Continue reading Different Enzymes to Digest Different Plant Substrates

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

The Endocannabinoid System of Animals

GwynneL.

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

Biomass from microalgae

GwynneL.

Biomass from microalgae: the potential of domestication towards sustainable biofactories SUMMARY: Microalgae could potentially be a renewable source of energy for people. Unfortunately, there are many issues right now with growing enough algae and keeping the process affordable (aka: it’s too expensive to grow and use algae commercially). The article is divided up into several… Continue reading Biomass from microalgae
