molecular identification of PDE4 splice variants which exhibit a variable distribution

[sofa]

Простите, что повторяюсь с вопросом, но очень хочется получить ответ, как это по-русски :(

Выражение встречается в следующем контексте:

The most recent reviews refer to 11 classes of cAMP PDEs and, in particular, the PDE4 subtype which is the form most frequently investigated for its potential in inflammatory diseases. This subgroup has been further divided following the molecular identification of PDE4 splice variants which exhibit a variable distribution and may offer a second layer of specificity against which new PDE4 inhibitors may be targeted.

Заранее боооольшое спасибо!!!
