Remdesivir, which is being tested against Ebola virus in the Democratic Republic of Congo, protected monkeys after exposure to Nipah virus in a small study published in Science Translational Medicine. About 70% of Niphah virus infections are fatal, no vaccine exists, and the only treatment is an experimental monoclonal antibody.
The Department of Defense has awarded a $2 million grant to the Texas Biomedical Research Institute to develop a Zika virus vaccine that is safe and effective in pregnant women. The research will be conducted on marmosets at the Southwest National Primate Research Center on the Texas Biomed campus.
Lab-made organoids transplanted into mice to replace lymph nodes connected to the existing lymphatic system and drained fluid normally, according to a study in Stem Cell Reports, and researcher Andrea Brendolan says he hopes the proof-of-concept study will lead to development of replacement lymph nodes for people to treat lymphedema. The researchers used collagenous extracellular matrices from cultured spleen stromal cells and seeded them with stromal cell progenitors from mice, and the matrices developed into lympho-organoids when transplanted into mice.
Marine biologists are seeking the best ways to raise octopuses and other cephalopods in captivity for gene, brain and other studies. The researchers have taken care to consider the cephalopods' welfare despite the absence of regulations regarding research on animals that have no backbone, says biologist Josh Rosenthal.
Vaccines that target the stalk of mushroom-shaped hemagglutinin in influenza viruses instead of the protein's cap have conferred protection in animal studies, and the results of a new study published in Nature Medicine suggest that the technique protects people as well. The protein's cap mutates rapidly, and targeting the stalk, which remains stable, could lead to a universal influenza vaccine.
Scientists in the UK prevented avian influenza from entering and replicating in chicken cells by editing a section of DNA inside the cells that produces the ANP32 protein. The next step is to ensure the change does not have unintended consequences before producing birds with the edited gene.
More than 1,000 people in Mexicali, Mexico, have been diagnosed with Rocky Mountain spotted fever since 2008, and researchers found that nearly 75% of the 284 dogs examined had at some point been infected with the tick-borne bacteria that cause the disease. Researchers reported in the American Journal of Tropical Medicine and Hygiene that 80% of Mexicali residents had heard of RMSF, but more than half did not use tick preventives, and the researchers say a northward migration of infected ticks is possible due to climate change.
Longstanding gender stereotypes discouraged the use of female animals in biomedical research, to the detriment of women's health, and those stereotypes continue to introduce bias into study design and conclusions now that researchers are required to use female subjects, neuroscientist Rebecca Shansky writes in a perspective piece published in Science. The assumption that males are the standard or reference population and females are odd is flawed, says neurobiologist Daniela Pollak, and conclusions from studies based on gender stereotypes encourages dangerous practices, says neuroscientist Ann Fink.
Animal rights groups mislead the public about animal research, but FBR is fighting back with facts. In this resource, highly respected neuro-oncologist and FBR Board Vice-Chair Dr. Henry S. Friedman refutes myths surrounding animal research with scientific evidence and sets the record straight on the reality and benefits of animal research. Check it out.
For 35 years, FBR has advanced biomedical research for the sake of both human and animal health. We can't do our job without your support. Please give what you can. Together we will continue to make a difference.
To take myself too seriously is the gentle kiss of death.
