The first large, real-world study of the effectiveness of mRNA COVID-19 vaccines during pregnancy found these vaccines, especially two initial doses followed by a booster, are effective in protecting against serious disease in expectant mothers whether the shots are administered before or during pregnancy.

Researchers have underpinned the molecular mechanism behind the immune system's "off switch", contributing to global efforts to design immune-boosting treatments.

Combining microbiology with engineering technologies, this novel 3D model uses a single microfluidic chip to study the complicated processes that take place in malaria-infected placenta as well as other placenta-related diseases and pathologies.

Creating a mutation that inhibits how the bacterial pathogen Neisseria gonorrhoeae causes gonorrhea, a common sexually transmitted infection, could offer a new way to prevent and treat the disease, according to researchers in the Institute for Biomedical Sciences at Georgia State University.

New research indicates that viruses are able to sense their environment to decide when to multiply and kill the host cell, adding a new dimension to viral-host interactions.

Researchers have discovered a drug candidate that, in mice, can prevent lethal lung inflammation by inhibiting a protein called PTP1B.

Tiny nets woven from DNA strands can ensnare the spike protein of the virus that causes COVID-19, lighting up the virus for a fast-yet-sensitive diagnostic test.

Through two studies, researchers have made stronger connections between gum disease and Alzheimer’s disease.

Researchers have investigated how the chronic inflammation that accompanies aging is regulated, identifying a positive feedback loop that maintains inflammation as we age.
