Our immune system is divided into two main branches: innate and adaptive. Innate immune cells act as a first line of defense, quickly responding to invaders, while adaptive immune cells take a longer ...

An evolutionary perspective on immune priming across plants and invertebrates highlights the roles of microbiomes and epigenetic regulation in shaping innate immune memory with promising applications ...

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 ...

Humans are protected by two branches of the immune system. Innate immunity provides built-in defense against widespread characteristics of bacteria and viruses, while adaptive immunity memorizes ...

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 ...

The immune-boosting power of a fever is surprisingly ancient. Cold-blooded creatures like fish typically move to warmer environments to help fight infections. In one fish species, Nile tilapia, that ...

The immune system’s primary responsibility is to recognize and target invading pathogens. Various immune cells are orchestrated to carry out this responsibility. Additionally, these cells are ...

Every day, we are exposed to a wide array of potentially harmful microorganisms — such as colds, the flu and even COVID. But our immune system — a network of intricate pathways within our body — helps ...

Smoking does not do a body good. We’ve known this universally acknowledged truth for at least the past 60 years. Still, researchers are constantly finding new ways that it harms our health. In a study ...
