Cells called neutrophils, which are considered the immune system's «first line of defense» because they react strongly to foreign invaders that enter the skin through a cut or other injury, were also surprisingly important.

It has long been known that the membranes encasing the brain, called the meninges, are loaded with T cells and other immune cells.

Besides the reduced numbers of helper T cells in the DLNs, the researchers also found that the lymph node environment in older mice contained lower levels of immune stimulators (so - called chemokines) and therefore was less capable of attracting other immune cells necessary for germinal center formation.

The cells produce chemicals, called cytokines, which then stimulate other immune system cells.

They have detected, for example, revved up signaling molecules involved in inflammation, such as tumor necrosis factor α (TNFα) and other cytokines; skewed populations of natural killer cells and other immune cells; imbalances in the protein - destroying enzymes called proteases; and a shortening of the telomeres, the «end caps» on chromosomes, which indicates prematurely aged cells.

Shortly after infection, HIV levels skyrocket, but then the immune system and other antiviral factors produced by cells drive down the amount of virus in the blood — the so - called viral load — and establish a «set point.»

If a previous virus invades again, the T cells can quickly kill infected cells and make chemical signals, called cytokines, to call in other immune cells for reinforcement.

In a typical immune response, for instance, inflammatory proteins called cytokines will be released by immune cells at a site of inflammation and then other immune cells will use these cytokines like a trail of breadcrumbs to home in on the site of infection and destroy the pathogens that are causing it.

Once inside, the virus's DNA acts as a danger signal that activates a protein called caspase 1, which can initiate cell death in several ways, including opening pores that disturb the cell's ion balance and releasing inflammatory signals that recruit other immune cells.
