Human Monoclonal Antibodies That Target the RH5 Complex of Blood-Stage Plasmodium Falciparum

249 million people were afflicted with malaria in 2022. There are five Plasmodium parasite species that cause malaria in humans. Of the five, Plasmodium falciparum causes most of the incidence of human disease. Most advanced malaria vaccine candidates can confer only partial, short-term protection in malaria-endemic areas. The pathogenesis of malaria is associated with blood-stage infection and antibodies specific to the parasite blood-stage antigens may be able to control parasitemia.

Human Monoclonal Antibodies That Target Plasmodium Falciparum Sporozoites

Malaria is one of the worlds deadliest infectious diseases, causing an estimated 249 million cases and 608,000 deaths annually, with children in the regions of Africa and South Asia being most vulnerable. Approx 2,000 cases of malaria are reported in the United States each year, by travelers from malaria-risk countries. Malaria is a mosquito-borne parasitic disease transmitted through the bite of infected female mosquitoes, which introduces Plasmodium sporozoites into the bloodstream of the human host.

A Rapid Method for Producing Antibodies

Antibodies are specialized proteins produced by the immune system which target and neutralize foreign materials, such as viruses or bacteria. Antibodies have a variety of useful applications in diagnostics, therapeutics, and as research reagents. Despite their widespread use there is no standard method to produce antibodies, and currently available methods are labor and time intensive.

EV-D68 Monoclonal Antibodies Isolated from Immunized Rhesus Macaques

Enterovirus D68 (EV-D68) has been linked to the widespread outbreaks of respiratory illness and acute flaccid myelitis (AFM) in the United States and Europe in 2014, 2016, and 2018. Although EV-D68 is now the most frequently encountered enterovirus (41.1% of cases), with an estimated global prevalence of 4%, there are no specific, FDA-approved therapeutic interventions targeting this virus.

Anti-Nucleoprotein Crimean-Congo Hemorrhagic Fever Virus Monoclonal Antibodies for Assay Creation

Crimean-Congo hemorrhagic fever (CCHF) is the most widespread form of viral hemorrhagic fever, found in Eastern and Southern Europe, the Mediterranean, northwestern China, central Asia, Africa, the Middle East, and the Indian subcontinent. Typically beginning with non-specific fever, myalgia, nausea, diarrhea, and general malaise, symptoms of infection with the tick-borne CCHF virus (CCHFV) can rapidly progress to hemorrhagic manifestations, with case fatality rates as high as 30-40% in some regions.

Immortalized Rhesus macaque Bcl-6/Bcl-xL Stable B Cell Lines as Tools for HIV Antibody Discovery

Scientists at NIAID have developed two immortalized stable B cell lines from rhesus macaques that can have value as research tools for the discovery of neutralizing antibodies of simian origin against HIV and that may have value in the development of an HIV vaccine. These B cell lines encode human Bcl-6 and Bcl-xL proteins, which are major regulators of apoptosis. These B cell lines are derived from the lymph node of a rhesus macaque (RM) that was infected with SHIV.CH505.

Hybridoma C4H3, Monoclonal Antibody to a Specific Peptide-MHC Class II Complex

T lymphocytes play an important role in the immune system by recognizing foreign protein motifs on cells. T lymphocytes are stimulated to recognize these motifs through their interactions with peptide-MHC complexes (pMHC). Thus, studying pMHC is an important aspect of understanding how the immune system works, particularly with regard to the development of vaccines. Unfortunately, the detection of pMHC is largely dependent on indirect assays, due to the difficulty of producing antibodies for specific pMHC.
