This invention relates to a method of selecting a collection of frame-shift peptides (CFSPs) to produce a universal cancer vaccine peptide collection (CVP) for prophylaxis and treatment of patients with hereditary and sporadic micro-satellite instability (MSI) tumors. This invention relates as well to a method of producing a CVP by selecting a subset of frame-shift peptides (FSPs) from the CFSP and optionally modifying the FSP's amino acid (aa) sequence to generate modified FSPs (mFSPs). The invention further relates to nucleic acid collections encoding a CVP of FSPs and/or mFSPs in one or more vaccine vectors that can be used also simultaneously. These CVPs, nucleic acids and vectors are used for the prophylaxis or treatment of MSI cancers.

The present invention relates to lentiviral particles which have been pseudotyped with Nipah virus (NiV) fusion (F) and attachment (G) glycoproteins (NiVpp-F/G). Additionally, the present invention relates to truncated NiV-F glycoproteins useful in producing such NiVpp lentiviral particles, as well as to additional variant peptides which enhance activity. Further, the present invention relates to methods of using such lentiviral particles or sequences, for example in the treatment of cancer or CNS disorders.

The disclosure discloses an in-vivo continuous directed evolution system and application thereof, and belongs to the fields of gene engineering and enzyme engineering. The system includes Escherichia coli host bacteria carrying a random mutation module mutagenesis plasmid, a programmed death module toxin-antitoxin system and a target gene expression module target plasmid. The modules are coupled with one another, and target genes are subjected to multiple rounds of continuous mutation by virtue of the random mutation module mutagenesis plasmid in the system, so that the mutation rate of the target genes is further increased, and ultimately, efficient evolution and screening of the target genes in the host bacteria are realized. According to the system, mutations are accurately positioned on the target genes, random mutations in non-target gene regions are reduced, and the system has good practical value and can be applied to directed evolution of various different functional proteins.

Various embodiments of the present invention are directed to the field of treating and preventing osteoporosis, with particular embodiments directed to a method of ameliorating, treating, or preventing osteoporosis in a human subject employing tomatidine, xylitol, rapamycin, etc., as well as modifying an individuals microbiome to reduce the likelihood of osteoporosis.

Provided herein are novel anti-CD28×anti-B7H3 (also referred to as “αCD28×αB7H3”) heterodimeric bispecific antibodies and methods of using such antibodies for the treatment of cancers. Subject αCD28×αB7H3 antibodies are capable of agonistically binding to CD28 costimulatory molecules on T cells and targeting to B7H3 on tumor cells. Thus, such antibodies selectively enhance anti-tumor activity at tumor sites while minimizing peripheral toxicity. The subject antibodies provided herein are particularly useful for enhancing anti-tumor activity when used in combination with other anti-cancer therapies.

Methods of making and using bacterial display polypeptide libraries using circularly permuted OmpX (CPX) variants are disclosed. The invention further relates to methods for enhancing the display of proteins and peptides at the surface of bacteria by optimizing linkers and incorporating mutations at positions 165 and 166 of CPX.
