Study suggests the need to characterize patient-specific responses to respiratory syncytial virus

Researchers at Baylor College of Medicine found that while most individuals responded to respiratory syncytial virus (RSV) natural reinfection with a typical sustained antibody response associated with protection, a few individuals surprisingly responded atypically, not being able to sustain the antibody response, which declined to levels that made the individuals susceptible to RSV reinfection.

Plants may control the genetics of intimate root symbionts

Researchers from the University of Ottawa have discovered that plants may be able to control the genetics of their intimate root symbionts - the organism with which they live in symbiosis - thereby providing a better understanding of their growth.

Fecal microbiota transplant helps cancer patients respond to immunotherapy

For patients with cancers that do not respond to immunotherapy drugs, adjusting the composition of microorganisms in the intestines--known as the gut microbiome--through the use of a stool, or fecal, transplants may help some of these individuals respond to the immunotherapy drugs, a new study suggests.

Researchers identify key molecule involved in immune regulation

The majority of the molecules in human bodies support the immune system to keep individuals healthy but they do so without reacting excessively, as this may otherwise drive the immune cells to cause problems, like autoimmune disorders.

Immunity of COVID-19 patients may rely on antibodies from previous coronavirus infections

The results of a study led by Northern Arizona University and the Translational Genomics Research Institute (TGen), an affiliate of City of Hope, suggest the immune systems of people infected with COVID-19 may rely on antibodies created during infections from earlier coronaviruses to help fight the disease.

Antibiotic resistance may be spreading much faster than expected

Pathogenic bacteria in humans are developing resistance to antibiotics much faster than expected. Now, computational research at Chalmers University of Technology, Sweden, shows that one reason could be significant genetic transfer between bacteria in our ecosystems and to humans. This work has also led to new tools for resistance researchers.
