Grape seed extract attenuates lung parenchyma pathology in ovalbumin-induced mouse asthma model: An ultrastructural study

► We detail lung ultrastructural remodeling in ovalbumin-induced asthma. ► We examine the ability of grape seed extract to ameliorate this pathology. ► Ovalbumin caused pathological alterations in lung parenchyma. ► Lung remodeling was suppressed by grape seed extract. ► GSE has protective and therapeutic potential to attenuate lung remodeling.
