Bad antibodies made good: The immune system's secret weapon uncovered. The 'bad apples' of the immune system are also its secret weapon, according to major new research. Scientists have revealed how a population of 'bad' antibodies in the immune system -- which are usually 'silenced' because they can harm the body -- can provide crucial protection against invading microbes.

How immune cells kill bacteria with acid. The first line of immune defense against invading pathogens like bacteria are macrophages, immune cells that engulf every foreign object that crosses their way and kill their prey with acid. However, it is not yet entirely understood how the acidification process is established. In their quest to systematically study proteins that transport chemicals across cellular membranes, researchers characterized the critical role for transporter SLC4A7, providing valuable new insights for many pathologic conditions.

Its just amazing how the human body works and how all these tiny cells know what to do and how to do it to keep us healthy.
