How long do strep antibodies stay in blood?
Antibodies are produced approximately a week to a month after the initial strep infection. ASO levels peak at approximately 4 to 6 weeks after the illness and then taper off but may remain at detectible levels for several months after the strep infection has resolved.
What causes strep infection?
Strep throat is caused by infection with a bacterium known as Streptococcus pyogenes, also called group A streptococcus. Streptococcal bacteria are contagious. They can spread through droplets when someone with the infection coughs or sneezes, or through shared food or drinks.

What are post streptococcal complications?
The initial infection might only cause a sore throat, fever, and rash, but poststreptococcal disorders can lead to many different problems. The exact disorder depends on which part of the body is attacked by your immune system. The disorder can affect the kidneys, heart, skin, brain, or joints.

How do ASOs affect DNA?
They can then, in effect, “turn down” a gene, disrupting the cell’s natural production of a particular protein. This is useful in treating genetic conditions, where mutations in our DNA can cause cells to produce harmful proteins or prevent them from producing those that our body needs to function.
Why are ASOs not mutually exclusive?
ASOs, because they work by preventing a cell from making a specific protein, have shown promise for treating gain-of-function mutations. They can target cells that are producing toxic proteins and stop them.
Can ASOs fix a protein?
ASOs can reduce or eliminate a protein we don’t want, but they generally can’t bring back or fix a protein that isn’t fulfilling its function, with some exceptions.
Can ASOs be used for loss of function?
While ASOs may have more potential for gain-of-function mutations, other treatments, including viral gene therapy and small molecule compounds, could possibly treat loss-of-function mutations. Combining therapies targeting each type of mutation could be a strategy for future approaches to ALS treatment.
