The process by which phages—viruses that infect and replicate within bacteria—enter cells has been studied for over 50 years. In a new study, researchers from the University of Illinois Urbana ...

You are about to create a live-attenuated vaccine, which means that you need to alter a pathogen—in this case a measles virus—so that it will still invade cells in the body and use those cells ...

Bacteria steal DNA from silent viruses and use it like a memory bank. That memory helps them protect future generations.

Some B and T cells become memory cells that can quickly identify and fight a future invasion by the virus. TIME ELAPSED: 6–11 DAYS The Virus Takes Countermeasures SARS-CoV-2 uses several tactics ...

During infections, the immune system needs to distinguish foreign antigens that are expressed by invading bacteria and ...

As the tunnels develop and connect neighboring cells, a path opens for the virus to invade new cells.” “Zika is the only virus in its family, which includes dengue and West Nile viruses among ...

The smallpox vaccine is a live vaccine; the cowpox viruses it contains will invade cells in your body, multiply, and spread to other cells in your body, just as the smallpox viruses would.

As the tunnels develop and connect neighboring cells, a path opens for the virus to invade new cells." "Zika is the only virus in its family, which includes dengue and West Nile viruses among ...

The virus infects nearby skin cells called keratinocytes ... What are Langerhans cells? Langerhans cells detect invading pathogens and display molecules from the pathogens, called antigens ...

New research shows how a specially trained population of immune cells keeps the peace by preventing other immune cells from attacking their own. The study provides a better understanding of immune ...

Our immune system works to fight infections immediately, but also maintain long-term immunity. Two waves of protection help ...

An immune system defect makes affected individuals vulnerable to severe viral diseases such as influenza or COVID-19. It is caused by the body's own antibodies, which inhibit important defense ...
