Cryptosporidium
           The protozoan that causes cryptosporidiosis. It is found in the
           intestines of animals and may be transmitted to humans by direct
           contact with an infected animal, by eating contaminated food, or by   C
           drinking contaminated water.

        CXCR4
           Chemokine receptor 4 (CXCR4, also known as fusin) is a protein
           on the surface of some immune system cells. It is one of two
           coreceptors that HIV can use along with the CD4 receptor to bind
           to and enter host cells. (The other coreceptor is CCR5.)

        Cytochrome P450 (CYP450)
           A system of enzymes, located primarily in the liver, that participates
           in the breakdown of drugs. Many drugs inhibit or enhance the
           activity of these enzymes. Any change in CYP450 enzyme activity
           may cause an increase or decrease in blood levels of drugs that are
           broken down through this system.
