One Pumpkin Pathogen Is so Successful It's Stopped Evolving, Say Scientists

According to new research, the pathogen that causes bacterial spot is so successful that it has had no reason to evolve through time or space.

Discovery of a New Enzyme Could Contribute to Novel Antibacterial Therapies

A bacteriophage-derived enzyme called endolysin is capable of targeting biofilms formed by Enterococcus faecalis, contributing to novel antibacterial therapies.

Liver Cells Put a “Sleep Timer” On Immune Cells in Chronic Hepatitis B Infection

A team has discovered that cells in blood vessels in the liver start a “sleep timer” that switches off immune cells, and targeting this mechanism could be a starting point for immunotherapies.

Researchers Create Novel Cell Type That Kills Cancer Cells in Research Models

Researchers have combined the genetic components of four types of cells to make a powerful new cell type, Co-STAR (Co-stimulatory Synthetic T-cell receptor and Antigen Receptor) cells. These cells were able to produce a sustained anti-tumor response against human cancer cells in laboratory studies.

Researchers Discover an Immune Defect in Lupus and a Possible Way To Reverse It

Researchers have uncovered a molecular defect that promotes the pathologic immune response in lupus, and have shown that reversing this defect could treat the disease.

Liver Tumor Microproteins Could Lead to Cancer Vaccines

A study has identified a group of small molecules that could be key to developing cancer vaccines. These microproteins are very small proteins expressed only by tumor cells and can activate immune cells against the tumor.

Hepatitis C Leaves Lasting “Scars” On the Immune System Even After Treatment

New research has provided insights into the lasting effects of chronic Hepatitis C virus (HCV) infection on the immune system.

Imaging Study Reveals Viral RNA Persists for Years in Tissues of Long COVID Patients

PET imaging reveals long COVID patients can possess leftover SARS-CoV-2 RNA in the gut years after infection. The findings add to mounting evidence that viral persistence and sustained immune activation are key factors underpinning long COVID.

Restored Oyster Beds Host More Marine Life

Biologists have found oyster sanctuaries that contain more abundant populations of oysters and other animal life not affected by the presence of two common parasites.

Platelets and Monocytes Communicate in Newly Discovered Immune Pathway

According to research platelets communicate with monocytes and increase their inflammatory capacity. By understanding the platelet-monocyte interaction, the team hope to improve the treatment of immune disorders and associated diseases.
