The present invention provides methods and compositions for inhibiting influenza infection and / or replication based on the phenomenon of RNA interference (RNAi) well as systems for identifying effective siRNAs and shRNAs for inhibiting influenza virus and systems for studying influenza virus infective mechanisms. The invention also provides methods and compositions for inhibiting infection, pathogenicity and / or replication of other infectious agents, particularly those that infect cells that are directly accessible from outside the body, e.g., skin cells or mucosal cells. In addition, the invention provides compositions comprising an RNAi-inducing entity, e.g., an siRNA, shRNA, or RNAi-inducing vector targeted to an influenza virus transcript and any of a variety of delivery agents. The invention further includes methods of use of the compositions for treatment of influenza.

This invention relates to a method of producing an auto induced biological barrier against spermatozoids and / or other microorganisms including viruses and / or pre cancers or non invasive cancers involving the production of an autoimmune reaction in a host in need of such auto-inducement. The invention is characterized in that it comprises the steps of producing heat shock proteins inside vaginal and cervical mucosal cells and releasing said heat shock proteins into the vaginal cavity thus inducing an autoimmune response through a trigger and / or stimulation of both innate and adaptive systems and, as a consequence, the production of: a contraceptive effect through the elimination of the migration or free movement of individual or populations of spermatozoids and / or an inhibition of the maturation and / or capacitation process of the same and / or a neutralization or destruction of the same; a prophylactic effect through an elimination of the migration or free movement of individual or populations of other microorganisms including viruses and / or a neutralization or destruction of the same; a prophylactic effect against pre cancers; a therapeutic effect against non invasive cancers. The invention also relates to a device for using said method comprising a hollow body (1) provided with a heat source on the inside as well as with a means (13, 27) of removal of said hollow body from the vaginal or rectal cavity and a means (6, 8, 10) capable of exchanging heat originating from the hollow body.
