Background

IL-15Ra chain is expressed by many cell types including monocytes, dendritic cells, natural killer cells, T cells and fibroblasts. Several isoforms of IL-15Ra exist and are generated either by alternative splicing or by proteolytic cleavage. Hence, IL-15Ra can be found as a membrane receptor or as a soluble receptor (sIL-15Ra); and as most isoforms of the receptor contain a sushi domain allowing very-high-affinity binding of IL-15, signaling or regulatory functions can be attributed to the receptor. Competition between soluble and membrane receptors can result in reduced biological activity of IL-15, though a super agonist effect of the soluble form was also observed. The signaling of IL-15 appears more complicated than for other cytokines because IL-15 primarily exists as a complex bound to IL-15Ra. When IL-15/IL-15Ra complexes are shuttled to the cell surface, they can stimulate opposing cells through the b/cC receptor complex (trans-presentation), or alternatively may allow an autocrine stimulation (cis-presentation).

Perfect and convenient tool
Size: Basic Frother, Color: Black
I am very happy with my new milk frother. Really easy to use and I was very pleased with the results. I got to enjoy my first home made cappuccino and it was perfect. I have only used the frother attachment so far but I plan to use the whip the next time I scramble a couple of eggs. Very please with my purchase.

I love this mixer
Size: Basic Frother, Color: Black
I love this mixer. I don't know how we got along before we had this. We have had this small hand mixer for 2 years, using it several times every day, day after day and it finally stopped working and I am ordering another one right now. I can't live without it. I make our bullet coffee with it. My wife makes her morning shake with it. I could go on and on but I need to get another one ordered right now.

Works perfectly!
Size: Basic Frother, Color: Silver
The first unit I got, the charging LED was not working so I don't know if the unit is charged. I returned the unit back to Amazon and got a brand new unit the next day. Great job, Amazon! The 2nd unit has been perform perfectly. I use it to whisk eggs in the morning to make French toasts, waffles, pancakes. All comes out perfect! Also, the mike froth for my morning latte and cappuccino. Don't under estimate this small unit, the spin is fast for high!!! I saw some negative review on the durability of the unit. I hope this is not the case. I'll update if anything changes. As for now, highly recommended!!!
