Colorectal cancer tumors are both helped and hindered by T cells – Fauna and Flora News

Colorectal tumors are teeming with white blood cells, but whether these cells help or hinder cancer is hotly debated. While some studies have shown that white blood cells heroically restrict tumor growth and fight colorectal cancer, equally compelling evidence presents white blood cells as malignant co-conspirators, reinforcing the tumor and helping it to spread. Now, …

Lymphatics Help “Seed” Early Zebrafish Brain Cells Psychology and Psychiatry News

In the embryonic stage of brain development, some neurons and synapses form correctly and connect, but others do not, resulting in parts and pieces being scrapped. This leaves dead or dying cells and requires the central nervous system to employ some type of cleaning crew. Microglial cells meet this challenge by “ingesting” waste products and …

ANTIBIORESISTANCE: An aberrant protein that kills bacterial cells

Because the protein is truly deadly for bacterial cells. Scientists describe how this ‘erroneously’ constructed protein mimics the action of aminoglycosides, a class of antibiotics. The protein could also serve as a model for a new class of antibiotics. A new strategy for controlling bacterial growth A chance discovery: Initially, the Brookhaven team, which specializes …
