The present disclosure relates to methods for transiently activating temperature-sensitive agents in one or more cells, for example by contacting one or more cells with a temperature-sensitive agent and transiently incubating the cells at a permissive temperature for inducing an activity of the temperature-sensitive agent in the cells. Additionally, the present disclosure relates to methods of contacting one or more cells in a subject with a temperature-sensitive agent and then lowering the subject's core body temperature to a permissive temperature for inducing an activity of the temperature-sensitive agent in the cells. The disclosure also relates to methods of contacting one or more cells in a subject with a temperature-sensitive agent, maintaining the subject's surface body temperature at a permissive temperature for inducing an activity of the temperature-sensitive agent in the cells. Further disclosed are methods of treating a subject with a temperature-sensitive therapeutic agent.
A composition for stimulating an immune response against an antigen in a mammalian subject, comprising an excipient and a temperature-sensitive agent (ts-agent) encoding the antigen, wherein the ts-agent is
A composition for stimulating an immune response against an antigen in a mammalian subject, comprising an excipient and a temperature-sensitive agent (ts-agent) encoding the antigen, wherein the ts-agent is a temperature-sensitive self-replicating RNA comprising an Alphavirus replicon lacking a viral structural protein coding region, and wherein the ts-agent is capable of expressing the antigen at a permissive temperature but not at a non-permissive temperature, and the antigen is a spike protein or fragment thereof of a coronavirus.
A temperature-sensitive agent (ts-agent), wherein the is-agent is
