Tricked-Out Immune Cells Could Attack Cancer
New cell-engineering technique may lead to precision immunotherapies.
Neural Networks Adapt to the Presence of a Toxic HIV Protein
HIV-associated neurocognitive disorders (HAND) afflict approximately half of HIV infected patients.
HIV Protein Manipulates Hundreds of Human Genes
Findings search for new or improved treatments for patients with AIDS.
Breaking the Brain’s Garbage Disposal
The children’s ataxia gene problem turned out to be not such a big deal genetically — it was such a slight mutation that it barely changed the way the cells made the protein.
Flesh-Eating Bacteria Work Together
Scientists recently discovered different strains of deadly flesh-eating bacteria working together to spread infection and they now have a better understanding of the role of the toxins they produce. The discovery could change how the illness and other diseases are treated.
Utilizing Antibodies from Ebola Survivors
A collaborative team from The University of Texas Medical Branch at Galveston, Vanderbilt University, The Scripps Research Institute and Integral Molecular Inc. have learned that antibodies in the blood of people who have survived a strain of the Ebola virus can kill various types of Ebola.
Antibiotic Use in Early Life Disrupts Gut Microbiota
The use of antibiotics in early childhood interferes with normal development of the intestinal microbiota, shows research conducted at the University of Helsinki.
Easier Diagnosis for Fungal Infection of the Lungs
A new clinical imaging method developed in collaboration with a University of Exeter academic may enable doctors to tackle one of the main killers of patients with weakened immune systems sooner and more effectively.
Mitochondrial Troublemakers Unmasked in Lupus
Drivers of autoimmune disease inflammation discovered in the traps of pathogen-capturing white blood cells.
Important Regulator of Immune System Decoded
Plasma cells play a key role in our immune system. Now scientists at the Research Institute of Molecular Pathology (IMP) in Vienna, Austria, and at the Walter and Eliza Hall Institute (WEHI) in Melbourne, Australia, succeeded in characterizing a central regulator of plasma cell function.

Direct Visualisation, Sizing and Counting of Aggregation in Proteins

NanoSight Ltd

A wide variety of aggregates are encountered in biopharmaceutical samples ranging in size and characteristics (e.g., soluble or insoluble, covalent or noncovalent, reversible or irreversible). Protein aggregates span a broad size range, from small oligomers (nanometers) to insoluble micron-sized aggregates that can contain millions of monomer units. 

Protein aggregation can occur at all steps in the manufacturing process (cell culture, purification and formulation), storage, distribution and handling of products. It results from various kinds of stress such as agitation and exposure to extremes of pH, temperature, ionic strength, or various interfaces (e.g., air–liquid interface). High protein concentrations (as in the case of some monoclonal antibody formulations) can further increase the likelihood of aggregation. 

Therefore, aggregation needs to be carefully characterised and controlled during development, manufacture, and subsequent storage of a drug substance and formulated product. Similarly, by monitoring the state of aggregation, modification or optimisation of the production process can be achieved.
