Immunoassay for the Simultaneous Detection of Functional Antibodies against Multiple Serotypes of <em>Streptococcus pneumoniae</em> and Other Bacteria Types

Streptococcus pneumoniae, or pneumococcus, is a type of bacteria that causes pneumococcal disease. Pneumococcal infections can range from ear and sinus infections to pneumonia and bloodstream infections. Children younger than 2 years old and adults 65 years or older are among those most at risk for disease.

Simple and Rapid Loop-Mediated Isothermal Amplification (LAMP)-based Assay for <em>Mycoplasma pneumoniae</em> Detection

Mycoplasma pneumoniae (M. pneumonia) can cause several different types of infection including chest colds and pneumonia. M. pneumoniae is a leading cause of community-acquired pneumonia. People of all ages are at risk for getting M. pneumonia infection, but it is most common among young adults and school-aged children. Current methods of detecting this agent are laborious and time consuming, so testing is not usually performed. However, knowing whether someone has M. pneumoniae infection is important for choosing the right antibiotic for treatment.

Optimized Variants of the Broadly Neutralizing HIV-1 gp41 Antibody, 10E8

Scientists at the National Institute of Allergy and Infectious Diseases (NIAID) recently discovered a human neutralizing antibody, 10E8, that binds to the GP41 protein of HIV-1 and prevents infection by HIV-1. 10E8 potently neutralizes up to 98% of genetically diverse HIV-1 strains.

By engineering the 10E8 antibody, NIAID scientists have improved the properties of 10E8 that affect manufacturability, such as solubility, while preserving its neutralizing breadth and potency.

Recombinant HIV-1 Envelope Proteins and Their Use

An effective human immunodeficiency virus type 1 (HIV-1) vaccine has long been sought to contend with the Acquired Immunodeficiency Syndrome (AIDS) pandemic.

One approach researchers have taken to elicit broadly neutralizing antibodies against HIV-1 is to stabilize the structurally flexible HIV-1 envelope (Env) trimer. Researchers stabilized the Env trimer in a conformation that displays predominantly broadly neutralizing epitopes and few non-neutralizing epitopes. Currently, BG505 DS-SOSIP is a leading vaccine candidate with the desired conformation and antigenicity.

Encapsulated Streptococcus Compositions and Methods for Pneumococcal Vaccine, Probiotic, and Diagnostic Assay Development

Streptococcus pneumoniae (S. pneumoniae) bacteria, or pneumococcus, can cause many types of illnesses. These range from ear and sinus infections to life-threatening conditions such as pneumonia, bloodstream infections, and meningitis. Pneumococci are surrounded by a polysaccharide capsule, which is thought to help it evade the immune system. Presently, over 90 known serotypes of S. pneumoniae have been identified, of which only a minority produce the majority of pneumococcal infections; a serotype is defined by a unique pneumococcal capsule structure.

A High-Yield Perfusion-Based Transient Gene Expression Bioprocess

Currently, fed-batch processes are the most commonly used bioprocesses in transient gene expression (TGE) vaccine manufacturing. However, because fed-batch processes keep all the cells and protein product in the vessel throughout the run, some limitations are intrinsic. First, waste products like cell debris or other unwanted small molecules accumulate in the vessel with a potential to disrupt the cell growth, protein production, and the stability of the generated protein of interest.
