Arising in the mucous membranes, these white patches on the tongue, gums, cheeks, or elsewhere inside the mouth have the potential to develop into squamous cell carcinoma. They may be caused by sources of chronic irritation, such as habitual alcohol consumption or tobacco use, or rough edges on teeth or dentures.
Virus infection in vertebrates results in two general types of immune response. The first is a rapid-onset innate response against the virus, which involves the synthesis of proteins called interferons and the stimulation of natural killer lymphocytes.
Immune Defense against Bacterial Pathogens: Innate Immunity (page 2) (This chapter has 6 pages) Â© Kenneth Todar, PhD. Innate Immunity. Innate Immunity is a form of non specific host defense against invading bacteria. It is natural or innate to the host, depending, in part, on genetics. Innate defense mechanisms are contitutive to the host, meaning they are continually ready to respond to invasion and do not require a period of time for induction.
