Some incredible sites on the immune system
and related research.
http://rampages.onramp.net/~keng/macrophage/macfunctions.html#cytokines
Cytokines are proteins produced by many cells within the body.
Their function is as messengers between cells. They signal
other cells to become activated, call cells into an area of
infection, hold cells in the area, signal cells to prepare
for an invading organism, and induce damage or death in cells
encountering them.

The wonderful world of the Macrophage!

A macrophage ingests bacteria as part of the immune response
to infection. Inside this white blood cell, bacterial proteins
are degraded into peptides and presented as antigens by specialized
molecules on the cell's surface. The ways in which cells turn
their own and foreign proteins into antigens have gradually
been revealed in recent decades. The macrophage is the large,
yellowish cell with projections; the bacterial cells are small,
rod-like, blue cells.

Visit cellsalive and see a time elapsed clip of the
CTL in action. Cytotoxic T lymphocytes (CTL) recognize surface
markers on other cells in the body that label those cells
for destruction. In this way, CTLs help to keep virus-infected
or malignant cells in check.

Penicillin kills bacteria by interfering with the ability
to synthesize cell wall. In this sequence, Eschericia coli
were incubated in penicillin for 30 minutes. The bacteria
lengthen, but cannot divide. Eventually the weak cell wall
ruptures. Check this site out.
