Transplantation of haematopoietic stem cells has been attempted in order to restore GM-CSF-dependent signalling in mice, but despite the positive results gained, this procedure required aggressive immunosuppression and myeloablation, which predisposed the patient to develop either respiratory infections, graft versus host disease or drug toxicity.

Sign In or Create an Account. Congenital PAP occurs as a respiratory disease that can emerge in neonates and children but also in adults, is characterised by different levels of surfactant accumulation, and is always associated with pulmonary fibrosis [ 23 ]. During inhaled GM-CSF therapy, the local deposition of the drug within the alveoli permits a direct activity against neutralising autoantibodies.

Since symptoms of PAP are not specific, pulmonary alveolar proteinosis congenital hypothyroidism and delayed diagnoses are more frequent. The progression of the disease is very variable, ranging from asymptomatic forms diagnosed with chance to early-onset forms that progress rapidly and result in uncontrollable respiratory failure [ 16 ]. As the knowledge about this rare disease increases, the role of novel therapies is likely to be better defined and optimized.

ABCA3 is a member of the ABCA transporter family known to be involved in transmembrane transport of endogenous lipids; it is expressed in the type II alveolar cells and is mostly detected at the limiting membrane of the lamellar bodies, where the surfactant complex is assembled, processed and stored [ 623 ].

Moreover, the use of advanced methods of genome engineering for targeted editing could guarantee an efficient and safe gene correction, which could be applied to stem cell-based gene therapy [ 43 ]. Furthermore, GM-CSF neutralisation results in impaired antimicrobial activity of neutrophils with increased risk of infections [ 1718 ].
