  • Data from coronavirus infections in animals and humans emphasize the generation of a high-quality T cell response in protective immunity. (nih.gov)
  • It's also the first time we've had an approach capable of yielding broadly neutralizing antibodies against HIV in humans," he says. (sciencedaily.com)
  • However, animal studies suggest that antibodies may not be enough to protect humans from pneumonic plague. (scienceblog.com)

  • 1- 4 Evidence from animal models suggests that an altered immune response to the commensal microflora of the host plays a central role in the development of the condition. (bmj.com)
  • Given our ability to encode any desired antibody into these vectors, we may be able to produce effective preventive treatments against a wide range of infectious diseases from malaria to COVID-19," he says. (sciencedaily.com)
  • 3, 5- 8 Animal models of inflammatory bowel disease (IBD), using knockout or transgenic mice, only acquire characteristic lesions when their colon is populated with normal commensal bacteria, 9- 15 while germ free mice with genetic susceptibility do not develop disease. (bmj.com)
  • The experienced staff of Abbiotec processes a custom project with the same mindset and tools that it develops antibody products for the Abbiotec catalog: we want an antibody that specifically detects the antigen in the chosen application. (abbiotec.com)
