Pneumonia is a lung infection that can be caused by viruses, bacteria or fungi and can result in millions of hospitalizations and deaths annually. Thus, to address drug-resistant infections, pharma and biotech companies are developing novel treatments such as bacteriophage therapies, immunomodulators and monoclonal antibodies.
Researchers have known for some time that maternal breast milk provides critical nutrients for newborns, and antibodies from mothers vaccinated against a specific disease-causing bacterium or virus can be transferred via breast milk to babies.
Simply put, an antibody is a large, Y-shaped blood protein produced by plasma cells that the immune system uses to take down pathogens like bacteria – and of course, viruses like SARS-CoV-2.
If B cells are the munitions factories of the immune system, manufacturing antibodies to neutralize harmful pathogens, then the tiny biological structures known as germinal centers are its weapons-development facilities.
It has long been known that mothers greatly influence the development of the growing fetus by not only providing nutrients through the placenta, but also a growing list of biological elements including beneficial antibodies, gut bacteria and now, allergies. They reported their findings last week in the journal Science.
