Measles Virus Neutralized by New Human Antibodies
9 May
Summary
- Human antibodies capable of neutralizing measles virus found.
- Antibodies prevent virus entry, offering new treatment approach.
- Viral load reduced 500-fold in rodent models with antibody infusion.
In a significant medical advancement, researchers have identified human antibodies that can neutralize the measles virus. These antibodies effectively block the virus from infecting host cells, paving the way for novel prevention and treatment strategies against the highly contagious disease.
Detailed in a recent publication, these antibodies bind to crucial sites on the measles virus, including its fusion and attachment proteins, to inactivate it. Studies in rodent models demonstrated that an infusion of these antibodies, administered either before or shortly after infection, reduced viral loads by 500-fold.
One specific antibody, named 3A12, rendered the circulating virus undetectable in these models. This discovery holds particular promise for immunocompromised individuals and very young children who are not yet fully vaccinated or are too young to receive the vaccine. These groups currently rely heavily on herd immunity for protection.
Furthermore, the study sheds light on why females are more prone to autoimmune diseases. New research reveals sex-specific differences in immune systems, with over 1,000 genetic switches operating differently in female and male immune cells. This results in higher inflammatory pathway activity in females, increasing their predisposition to conditions like lupus and multiple sclerosis.
This heightened immune reactivity in females offers an advantage in fighting infections but comes at the cost of a greater susceptibility to autoimmune diseases. The findings underscore the importance of considering sex-specific differences in immunological research and treatment development to improve our understanding and management of diseases.
