What are aminocyclitols? How do they work? What are they inactive against? correct answer: -aminocyclitols belong to a class of dugs that are sugar-derived and that demonstrate important biological value -aminocyclitols are components that make up aminoglycoside-type antibiotics -they act on susceptible baceria presumably by irreversibly binding to the 30s ribosomal subunit, thus inhibiting protein synthesis. -antimicrobial activity of aminoglycosides is enhanced in alkaline environments. ...

An interferon is - a protein released by virally infected human cells to trigger production of antivirals in neighboring cells These antibodies are commonly found in mucus and are the most abundant in our body - IgA antibodies These cells have many identical antibodies on their surface that recognize a particular antigen. When activated the cells differentiate and proliferate into memory cells as well as plasma cells, which secrete antibodies - B cells Found on the surface of all nuclea...
