Instead of producing antibodies that attack infectious organisms, the body produces antibodies called autoantibodies that react with components of the body's own tissues.
Since psoriasis is sometimes initiated or exacerbated by a throat infection with streptococci and M protein is an important antigenic determinant, the authors speculate that T cells triggered by streptococcal proteins can cross-react with components from the lesional skin [42].
It enters the leaves through open stomata and due to its high reactivity immediately reacts with components of the apoplastic space generating various ROS and activating detoxification, including enzymatic and non-enzymatic antioxidants and other defense mechanisms [ 6, 7].
We noted that all DFA-positive specimens reacted with both components of the assay, suggesting that the sensitivities and specificities of the respective assays were similar, as we previously showed for cultures.
The two odour chemicals that were "lost" had chemically reacted with a component of the diesel exhaust, mono-nitrogen oxide, known as NOx.
The shift of peaks indicates that Ba chemically reacted with F-component species, which some Ba-O bonds are broken and a few Ba-F bonds are generated.
Timothy grass pollen allergen components are also known to cross-react with peanut components, but in this study Timothy grass pollen components did not lead to any confounding effects in relation to the association between Ara h 9 and bronchospasm.
Nitrogen and argon are constant along the reactor length because neither nitrogen nor argon reacted with any other components.
Six of nine anti-RPA-positive sera reacted with all three components of RPA; of the remainder, one reacted with RPA70 and RPA32, one reacted with RPA14 only, and one was negative.
Vapor phase components are inherently smaller/more reactive than particulate phase components and therefore have a higher likelihood of reacting with biological components immediately upon exposure as well as crossing phospholipid membranes more quickly than larger molecules.
