Last, but definitely not least, Macrophages—if outgunned—play the population card: they multiply rapidly. When they find themselves in an area of high cancer cell or viral particle density, they don’t have to call up the draft to get more troops; they simply clone themselves, which they can do on very short notice. More Macrophages automatically translates into more of all the other weapons enumerated above. But, again, this multiplication process occurs only in activated Macrophages.

Without VDBP, Macrophages languish. In the presence of Vitamin D Binding Protein, their activity level increases exponentially. Once activated, Macrophages multiply rapidly and attack ferociously.
