The innate immune system serves as the body's first line of defence, rapidly detecting and responding to external pathogens and internal damage. Recent advances in the field have highlighted the ...

Scientists generally agree that eukaryotes, the domain of life whose cells contain nuclei and that includes almost all multicellular organisms, originated from a process involving the symbiotic union ...

SARS-CoV-2 has an enzyme that can counteract a cell's innate defense mechanism against viruses, explaining why it is more infectious than the previous SARS and MERS-causing viruses. The discovery may ...

A new review by Dr. Ruyuan Wang and an international team of researchers explores the complex interactions between the innate and adaptive immune systems, shedding light on regulatory mechanisms in ...

When pathogens attack the body, the innate immune system goes to work protecting against the invading disease. The innate immune system is the first line of defense. It detects precisely what the ...

In recent years, the field of immunology has increasingly focused on the role of glycolipids and sphingolipids in the differentiation and function of innate immune cells, such as macrophages, ...

Taken together, these advances suggest that part of age-related immune decline is driven by specific, potentially reversible ...

During the recent Covid-19 pandemic, the rate of serious illness and death was jarringly high in older populations. Why? Weakening immune systems — as we age, we become more vulnerable to infections, ...

The newborn's immune system is a highly specialized mechanism that takes months to mature and become capable of effectively responding to pathogens. During this phase, adequate nutritional support, ...

Garlic has anti-inflammatory effects that can help with immunity. But foods like citrus fruits and fatty fish may be able to boost immunity even more.
