Innate Immunity Signal Transduction in Human Leukocytes

Open for Recruitment

Study Background

Innate Immunity Signal Transduction in Human Leukocytes

Open for Recruitment

The Innate Immunity Signal Transduction in Human Leukocytes is a research study to determine the response of immune cells from the bloodstream.

This study will investigate the response of immune cells to various signals in the test tube to determine how they sense the signals in the body and what substances they produce in response to them. It will determine how the cells may, under certain circumstances, contribute to inflammation, and will measure substances in the blood plasma (the liquid, non-cellular part of the blood) that might stimulate white blood cells, in order to understand how the blood responds to possible disease-related conditions.
