Noun
cytokine- any of varuious small regulatory proteins that regulate the cells of the immune system
cytokine
...Basically, the term "cytokine" has been used to refer to the immunomodulating agents (interleukins, interferons, etc.). Conflicting data exists about what is termed a cytokine and what is termed a hormone. Anatomic and structural distinctions between cytokines and classic hormones are fading as we learn more about each. Classic protein hormones circulate in nanomolar (10) concentrations that usually vary by less than one order of magnitude. In contrast, some cytokines (such as IL-6) circulate in picomolar (10) concentrations that can increase up to 1,000-fold during trauma or infection. The widespread distribution of cellular sources for cytokines may be a feature that differentiates them from hormones. Virtually all nucleated cells, but especially endo/epithelial cells and resident macrophages (many near the interface with the external environment) are potent producers of IL-1, IL-6, and TNF-α. In contrast, classic hormones, such as insulin, are secreted from discrete glands (e.g., the pancreas). As of 2008, the current terminology refers to cytokines as immunomodulating agents. However, more research is needed in this area of defining cytokines and hormones. Read full entry

How long does it take for I have read about it, and this
sems to be the biggest factor
for my concern.

ahh im wondering the same thing! if its a regular flu it's not that bad but cytokine storms means that teens and young adults will be affected the worst :-\ |

What is the relationship I heard they both have to do
with the amount of immune
cells in the body

cytokine storms are caused by a an over reaction of the immune system AIDs on the other hand are caused by HIV a Virus that attacks the immune system AIDS kills slowly while Cytokine storms are usually instant fatality but cytokine storms are treatable more effectively Cytokine storms are not sexually transmittable due to the fact a person suffering it will immediately see the effects and wont be in a condition for sexual intercourse |

How to preserve blood and/or I intend to collect blood
samples from large number of
mice for my experiment. I want
to preserve these samples for
several months because I may
will need later to check the
level of several protiens in
it (by western blot or ELISA).
What is the best way to
preserve it? Freezing? Whole
blood or serum or plasma? -80
degree or liquied nitrogen?
Thanks.

In our lab we draw the blood then spin it all down and separate it out, Plasma in on cryotube, buffies (wbc) in another, and RBCs in the last. All are then frozen at -80 until we need them. I have done experiements from blood that is 8 years old and still fine. Liquid nitrogen isn't needed if you only want to store for several months. |
