Mouse Anti-Mouse CXCL9 (Mig) Monoclonal Antibodies

This technology describes monoclonal antibodies against mouse chemokine (C-X-C motif) ligand 9 (CXCL9), also known as Monokine induced by gamma interferon (Mig). CXCL9 is a secreted protein that functions to attract white cells and increased expression of CXCL9 has been linked to several diseases. The inventors at the NIH generated over 100 anti-mouse CXCL9 antibodies from a CLXL9/Mig knockout mouse and further characterized several antibodies to show neutralization of CXCL9.

CXCR4 Reduction Leads to Enhancement of Engraftment of Hematopoietic Stem Cells

Methods of enhancing engraftment of donor hematopoietic stem cells (HSCs) by reducing expression or activity of CXCR4 in HSCs is described. HSC are the only cells in the bone marrow that are both pluripotent and long lived. Bone marrow transplantation (BMT) using HSC is an increasingly common medical therapy for severe hematologic cancers and primary hematologic immunodeficiencies. However, for significant HSC engraftment to occur there must usually be pre-transplant conditioning with either irradiation or chemotherapy or both.

Novel malaria vaccine candidates comprising engineered nanoparticles

Using proteins derived from the malaria Plasmodium falciparum parasite, NIAID has developed three different nanoparticle platforms to serve as scaffolds for displaying multiple copies of malaria antigens in an organized, repetitive manner to enhance vaccine effectiveness. The first platform uses the pyridoxal 5’-phosphate (PLP) synthase protein to form a nanoparticle displaying 48 copies of up to 4 different proteins. The second platform uses the chaperone 60 (Cpn60), which can display 28 copies of up to 2 different proteins.
