Background

CD64 (Cluster of Differentiation 64) is a type of integral membrane glycoprotein known as an Fc receptor that binds monomeric IgG-type antibodies with high affinity. It is more commonly known as Fc-gamma receptor 1 (FcγRI). After binding IgG, CD64 interacts with an accessory chain known as the common γ chain (γ chain), which possesses an ITAM motif that is necessary for triggering cellular activation. Structurally CD64 is composed of a signal peptide that allows its transport to the surface of a cell, three extracellular immunoglobulin domains of the C2-type that it uses to bind antibody, a hydrophobic transmembrane domain, and a short cytoplasmic tail. CD64 is constitutively found on only macrophages and monocytes, but treatment of polymorphonuclear leukocytes with cytokines like IFNγ and G-CSF can induce CD64 expression on these cells.

Used shoes
Size: 10 Little Kid, Color: Glitter Clear W/Strap, Size: 10 Little Kid, Color: Glitter Clear W/Strap
If I could give this zero stars, I absolutely would. I ordered these shoes expecting them to be brand new since I paid full price and never selected any “used” option. What I received instead were clearly heavily worn shoes there were visible signs of use that you simply wouldn’t expect from a new product.

Pricey but worth it
To say my daughter loves shoes would be an understatement and whenever you throw in a fun color and glitter to the mix, it only exponentially increases the love and excitement every time she puts on these shoes! The quality of the shoes are outstanding, they provide support in the right places and so far have been surprisingly durable (for a toddler that’s saying something)! This is the second pair of this shoe that I’ve purchased, the first was a pair of the clear glitter style. They are very cute shoes and the color matched the pictured on the website very well, which was great since I was trying to complete a “Princess Anna” look with a previously purchased dress. Note: I do suggest to size up one size, because in my experience they run a little small.
