Putoczki TL (2013): Targeting cytokines in inflammatory diseases
What are the cytokines secreted by Th2 (T-helper 2) cells
Cytokines (Greek cyto-, cell; and -kinos, movement) are small cell-signaling protein molecules that are secreted by numerous cells and are a category of signaling molecules used extensively in intercellular communication. Cytokines can be classified as proteins, peptides, or glycoproteins; the term "cytokine" encompasses a large and diverse family of regulators produced throughout the body by cells of diverse embryological origin.
The term "cytokine" has been used to refer to the immunomodulating agents, such as interleukins and interferons. Biochemists disagree as to which molecules should be termed cytokines and which hormones. As we learn more about each, anatomic and structural distinctions between the two are fading. Classic protein hormones circulate in nanomolar (10-9) concentrations that usually vary by less than one order of magnitude. In contrast, some cytokines (such as IL-6) circulate in picomolar (10-12) 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.
I can see soda cans,
Clanking off the back of our hippie van,
Driving to our log cabin house on the bay.
I can see us sitting there,
Rosy cheeks and long brown hair,
Collecting characters as they sway.
And where are you now,
when I'm dreaming all this out?
Does distance make the heart grow founder,
Or does it make it wander... Around,
You can't promise this won't tear me down.
You can hear me shout it out,
Well I hold a heart of... Doubt,
I doubt that loves real anyway,
Love, Love, Well you can hear me say...
It's tearing me down
Well hold the ring boy,
Love will make you drown.
Oh yeah, oh yeah.
I can see children,
Clinging to our knees cause where the ones they need.
And grandma and grandpa wouldn't know.
I can see them growing up,
Drinking up and throwing up,
Becoming wild gypsies like we.
And where are you now,
when I'm dreaming all this out?
Does distance make the heart grow founder,
Or does it make it wander... Around,
You can't promise this won't tear me down.
You can hear me shout it out,
Well I hold a heart of... Doubt,
I doubt that loves real anyway,
Love, Love, Well you can hear me say...
It's tearing me down
Well hold the ring boy,
Love will make you drown.
Love will make you drown
Love will make you drown
Can you tell me if this distance,
Makes loves to hard of a mission?
Suspicion is brewing, I'm wishing and fishing,
And thinking of a way, to get me out,
Game over angel, well here's a man down.
But oh wayt, can you tell if these feelings that I feel,
Are useless or witty, or maybe they are real.
I can't find a true answer in my head,
And I'm prancing around at the end!
I can see soda cans,
Clanking off the back of our hippie van,
Driving to our log cabin house on the bay.
I can see us sitting there,
Rosy cheeks and long brown hair,
Collecting characters as they sway.
But, It's tearing me down
Well hold the ring boy,
Love will make you...
It's tearing me down
Well hold the ring boy,
Love will make you drown.
