Described herein are peptides, compositions, and method of treating measles or HIV infection with antiviral peptide conjugates comprising a fusion inhibitory peptide (FIP) conjugated to a C-terminal heptad repeat (HRC) peptide. Also described herein are soluble stabilized measles F proteins, compositions, and method of preventing measles infection with the stabilized F protein, which can be administered alone, or in combination with the antiviral peptide conjugates described herein.

This invention comprises: compositions comprising a derivative, plasmids, a reagent kit and methods of making these compositions a derivative, vaccine- and non-vaccine-compositions of above for causing death of cancer cells that form part of a tunoour and virus infected Denguue, Measles and other diseased cells; the derivative comprising replicating as well as non-replicating dervivaties of an attenuated negative stranded RNA virus belonging to family paramyxoviridae, including Measles Virus, comprising a single additional transcriptional unit carrying either only one or two or more non-viral genes, and the non-replicating derivatives being free from contaminating replicating Measles Virus (b) a Measles Virus packaging cell line for making above compositions, expressing the M, F and H proteins of MV stably. And (c) a reagent kit for producing the Measles Virus derivatives describved above.

It is an object of the present invention to provide a medicament or a pharmaceutical composition, which is effective for the treatment of various cancers.

More specifically, the present invention relates to a pharmaceutical composition for use in the treatment of cancers, which comprises rMV-SLAM-blind or rMV-V(−)-SLAM-blind. The pharmaceutical composition has the effect of causing the regression of tumor, even if it is intravenously administered, and it also exhibits effects on cancer metastasized from a primary lesion.

Provided are immunostimulatory bacteria and oncolytic viruses, and pharmaceutical compositions containing the bacteria and/or viruses, that act as three prime repair exonuclease 1 (TREX1) antagonists. The bacteria and viruses are for treating tumors that are human papillomavirus (HPV) positive or that have a high tumor mutational burden (TMB). The immunostimulatory bacteria and oncolytic viruses encode therapeutic products such RNAi, such as shRNA and microRNA, that mediate gene disruption and/or inhibit expression of TREX1, or that inhibit TREX1. The bacteria contain additional modifications to enhance their anti-tumor activity. The bacteria and viruses are used for treatment of tumors in which TREX1 expression correlates with the presence of the tumor or properties of the tumor, such that inhibition of TREX1 advantageously treats the tumor.

The present invention provides compositions and methods for treating a measles virus infection. A pharmaceutical composition comprises a polypeptide in a biocompatible pharmaceutical carrier, in which the polypeptide consists of at least a portion of SEQ ID NO: 5 or SEQ ID NO: 6. A method embodiment comprises administering the polypeptide (preferably in a biocompatible pharmaceutical carrier) to a subject suffering from a measles infection.

This invention comprises: compositions comprising a derivative, plasmids, a reagent kit and methods of making these compositions a derivative, vaccine- and non-vacicine-compositions of above for causing death of cancer cells that form part of a tunoour and virus infected Denguue, Measles and other diseased cells; the derivative comprising replicating as well as non-replicating dervivaties of an attenuated negative stranded RNA virus belonging to family paramyxoviridae, including Measles Virus, comprising a single additional transcriptional unit carrying either only one or two or more non-viral genes, and the non-replicating derivatives being free from contaminating replicating Measles Virus (b) a Measles Virus packaging cell line for making above compositions, expressing the M, F and H proteins of MV stably. And (c) a reagent kit for producing the Measles Virus derivatives describved above.

Embodiments of the disclosure relate to the domain of virology of Paramyxoviruses. The disclosure concerns a method for producing self-assembling paramyxoviral particles and a method for identifying a compound able to inhibit the replication or the transcription of a Paramyxovirus. The disclosure also pertains to the nucleocapsid-like particles obtainable by the method of the invention and their use for biotechnological and pharmaceutical applications.

Methods, pharmaceutical compositions and vaccines comprising an attenuated bacteria that expresses a recall antigen are disclosed for treatment of cancer.
