infection

The causes of neurodegenerative diseases are largely mysterious, but the current thinking is that they involve inflammation, a normal function of the immune system that is usually short-lived in response to infections or wounds.

A research paper titled "Targeted recruitment of immune effector cells for rapid eradication of influenza virus infections" has been published in the peer-reviewed Proceedings of the National Academy of Sciences.

Ideally, a vaccine would teach the immune system to recognize the closed pre-fusion F protein so it could stop infection.

Pneumonia, when there is inflammation in the lungs because of an infection, is more common after cold weather, external.

Acute infections normally clear up spontaneously in patients with an intact immune system.
