SARS-CoV-2 can make itself unrecognizable to immune response by T-killer cells through mutations

The body's immune response plays a crucial role in the course of a SARS-CoV-2 infection. In addition to antibodies, the so-called T-killer cells, are also responsible for detecting viruses in the body and eliminating them.

Study shows causal relationship between neonatal antibody production and mother's microbiota

A healthy system of gut bacteria, or microbiota, is crucial to health: Gut bacteria not only aid with digestion, but also play an important role in the body's immune response. Infants, however, are not born with full-fledged gut microbiota, which makes it difficult for them to fight off intestinal infections.

Study reveals new mechanism through which cells build “mini-muscles”

Research teams have revealed how the motor protein, called myosin, which is responsible for causing the contraction of skeletal muscles, also functions in non-muscle cells.

Study provides new information on occurrence of DVL2 gene defect in dogs

A recent genetic study at the University of Helsinki provides new information on the occurrence of a DVL2 gene defect associated with a screw tail and its relevance to canine constitution and health.

Gut microbiome alterations help melanoma patients to respond to immunotherapy

Statistical modeling developed by Oregon State University researchers has confirmed that changes to melanoma patients' gut microbiome led them to respond to a type of treatment capable of providing long-term benefit.

Study: Cattle feed yards emit synthetic chemical cocktails into the environment

A recent Point of Reference article, "The meat of the matter: Environmental dissemination of beef cattle agrochemicals," published in Environmental Toxicology and Chemistry, points at synthetic chemical cocktails being emitted from cattle feed yards into the environment and how they can impact our ecosystem and our health.

Bacteriophage can play important role in microbial control

Crop plants and animals can be infected by bacterial pathogens that reduce yield, cause food wastage, and carry human pathogens that spread disease on consumption.

Gut cells raise alarm during parasite invasion

To effectively combat an infection, the body first has to sense it's been invaded, then the affected tissue must send out signals to corral resources to fight the intruder.

English rivers are extensively contaminate with neurotoxic pesticides used in veterinary flea products

Researchers at the University of Sussex have found widespread contamination of English rivers with two neurotoxic pesticides commonly used in veterinary flea products: fipronil and the neonicotinoid imidacloprid. The concentrations found often far exceeded accepted safe limits.

Genetically edited form of herpes simplex virus outperforms key vaccine candidate

A genetically edited form of a herpes simplex virus -- rewired to keep it from taking refuge in the nervous system and eluding an immune response -- has outperformed a leading vaccine candidate in a new study from the University of Cincinnati, Northwestern University and the University of Nebraska-Lincoln.

Researchers use digital endocasts technique to reconstruct surface morphology of canine brains

Based on digital endocranial cast models the canine brain does not increase proportionally with body size. Researchers at ELTE Eötvös Loránd and Kaposvár University in Hungary reconstructed the surface morphology of 28 canine brains, including various dog breeds, wolves, coyotes, and jackals.
