    Abstract: A composition for expressing a polypeptide within a target organ including a delivery particle, and at least a first mRNA sequence complexed with, encapsulated by, or otherwise associated with the delivery particle. The mRNA sequence includes a coding sequence which codes for the polypeptide, at least a first untranslated region (UTR) sequence, and at least one micro-RNA (miRNA) binding site sequence, wherein the miRNA binding site sequence is located within, immediately 5′ to, or immediately 3′ to, the first UTR sequence. The miRNA binding site sequence is selected so as to provide for differential expression of the coding sequence between first and second cell types comprised within the target organ. Methods for making and using the composition are provided, particularly in treatment of disease, such as cancer.

    Abstract: A method of treating a central nervous system cancer in a subject comprising administering to the subject a preconditioning agent, and, administering to the subject a therapeutic dose of an oncolytic virus; wherein the preconditioning agent is an immunostimulant selected from the group consisting of a toll-like receptor agonist, a subtherapeutic dose of an oncolytic virus, and/or an interferon that induces a transient anti-viral response and/or upregulates an interferon response; and wherein the preconditioning agent and the therapeutic dose of the oncolytic virus is administered to the subject's cerebrospinal fluid or periependymal region. Provided herein are methods of treating a central nervous system cancer in a subject. This method allows for intrathecal administration of oncolytic virus, which, until the present invention, resulted in unacceptable toxicity.
