Background

The cluster of differentiation 4 receptor (CD4) is a 55kDa type I integral membrane glycoprotein which plays a substantial role during adaptive immune responses. In T-cells, CD4 mediates maturation, stabilizes T-cell receptor interactions with peptide-major histocompatibility complex class II (MHCII) complexes on antigen presenting cells, and mediates intracellular T-cell signalling.2 In addition to T-cells, CD4 has also been shown to be expressed on monocytes, monocyte-derived macrophages, Langerhans cells, B lymphocytes, dendritic cells, eosinophils, megakaryocytes and mast cells. The role of CD4 during immune function can also be diverted by the human immunodeficiency virus type 1 (HIV-1) envelope glycoprotein gp120 as the viral receptor utilizes CD4 as the primary receptor as well as the co-receptor CCR5/CXCR4 during the entry process.

I love this milk frother, a must have for coffee lovers!
Color: Silver
I absolutely love this Bonsenkitchen milk frother! It creates the perfect foam in seconds and my coffee has never tasted so good. The rechargeable feature is so convenient and I love that it comes with a stand to keep it organized on my counter. It is easy to use, easy to clean and works perfectly every single time. If you love coffee at home this frother is a game changer, it makes you feel like you are at a coffee shop without spending a fortune. Highly recommend!

Does the job!
Color: Silver
Great frother. Love that it's rechargeable. 3 speeds, double frothing ring. This one is way better than my last, battery operated one. A lot of people giving are negative reviews or deductin stars because they think you have to cycle through the speeds to turn it off - they're wrong. You just hold the button for a couple of seconds and it turns off. Highly recommend!

Stand was my favorite part, hated how close off and higher speed is
Color: Silver
Well the first lesson is dont hit the power button to turn off, as it goes to 2nd speed and slings your drink everywhere. Im not happy with the stability of the brother, had better, as free with coffees. Positive is, it has a stand, it does have 3 speeds, just never needed the other two speeds, and if you dont hold power button long enough to turn off, it goes into higher speed.
