Immune systems are found in most living organisms. Immune is most medicine for Human.

They reflect the common challenges of existing in a potentially

hostile external environment, and often exhibit a complex,

ever-changing interplay between specialized cell types,

potent effector molecules, and exogenously acquired

molecules and organisms. In our own immune systems,

changes in the delicate homeostatic balance can lead to

major problems, such as allergic responses or autoimmune

diseases. Understanding how our immune system functions is

difficult because of the plethora of different cell types and

biomolecules involved, and because of its extremely dynamic

nature. It is in constant coevolution with pathogens and must

respond rapidly and specifically in each individual to a vast array

of potential threats. Two major limitations of human immune

system studies are their reliance on relatively few targeted

assays and their potentially limited diversity within the samples

examined. Research that can provide genuine answers for immunological questions may require a systems biology

approach that examines large numbers of different cell types and their interplay with real-time effector biomolecules, preferably using diverse sample cohorts.
