Background

Interleukin-13 is also known as IL-13. It is a protein that in humans is encoded by the IL13 gene. Interleukin-13 is an immunoregulatory cytokine produced primarily by activated Th2 cells.It is involved in several stages of B-cell maturation and differentiation. It up-regulates CD23 and MHC class II expression, and promotes IgE isotype switching of B cells. This cytokine down-regulates macrophage activity, thereby inhibits the production of pro-inflammatory cytokines and chemokines. This cytokine is found to be critical to the pathogenesis of allergen-induced asthma but operates through mechanisms independent of IgE and eosinophils.

Coneheads
The sweater is nice looking, but whoever designed the hoodie didn’t think straight. It’s sewn so that when the hood is pulled over the head, it forms a triangular shape. It is a hoodie suited perfectly for the characters in the movie The Coneheads.

Very nice & heavy sweater.
Size: X-Large, Color: Grey
Very nice and heavy sweater. Im 220lbs and ordered an X-tra large, which is very snug/tight as this is form fitting. Depending on your build, if youre around 220LB with a little bit of stomach maybe order up to get a better fit.

Superb hoodie for mechanics
Size: Large, Color: Dark Green
The #1 favorite hoodie of mechanics. Nice and thick which makes it very warm and durable, and a great fit. My mechanic son gets one of these every year for his birthday, and never wants any other brand.
