Autoimmune Pulmonary Alveolar Proteinosis
Autoimmune pulmonary alveolar proteinosis (aPAP) is a rare autoimmune lung disease characterized by the accumulation of surfactant proteins in the alveoli, leading to respiratory impairment. With our expertise in aPAP therapy development, our company is committed to pushing the boundaries of scientific knowledge and delivering innovative solutions.
Overview of Autoimmune Pulmonary Alveolar Proteinosis
Autoimmune pulmonary alveolar proteinosis (aPAP) is a rare lung disorder characterized by the abnormal accumulation of surfactant proteins and lipids within the alveoli. This accumulation leads to impaired gas exchange, causing respiratory symptoms such as dyspnea, cough, and fatigue. The pathogenesis of autoimmune PAP involves the disruption of granulocyte-macrophage colony-stimulating factor (GM-CSF) signaling, which plays a crucial role in the maintenance of alveolar macrophage function. Autoantibodies against GM-CSF have been identified in cases with PAP, leading to the neutralization of GM-CSF and subsequent impairment of macrophage-mediated clearance of surfactant proteins.

Therapeutics Development for Autoimmune Pulmonary Alveolar Proteinosis
Historically, various empiric therapies, including antibiotics, corticosteroids, and physical dissolution techniques, were attempted in the management of PAP. However, with the discovery of the role of GM-CSF in PAP pathogenesis, therapeutic strategies have shifted towards GM-CSF augmentation, plasmapheresis, and anti-B lymphocyte therapy. One of the most effective therapeutic modalities for aPAP is therapeutic lung lavage, also known as whole lung lavage (WLL). In addition to WLL, GM-CSF augmentation therapy has emerged as a potential therapeutic option for PAP. Recombinant GM-CSF administration can help restore alveolar macrophage function and improve surfactant clearance.

Our Services
Equipped with a highly skilled team and cutting-edge platform, our esteemed organization offers comprehensive and integrated solutions for the development of therapies targeting autoimmune pulmonary alveolar proteinosis.
In addition, our company offers a wide range of preclinical research services to support the development of potential therapies for autoimmune PAP. These services include pharmacokinetic studies, toxicology assessments, efficacy evaluations, and formulation optimization.
Rasgrp1-Deficient Mouse Models
Our team of highly skilled scientists at our company has dedicated extensive efforts to develop and refine the Rasgrp1-deficient mouse model. By targeting the Rasgrp1 gene, which encodes a key protein involved in immune signaling pathways, we can create a mouse model that exhibits characteristics resembling human aPAP.
At our company, our team of expert scientists develop cell-based models for studying aPAP. Using primary alveolar macrophages isolated from both healthy donors and patients with Autoimmune pulmonary alveolar proteinosis (PAP), we have created a platform that closely mimics the disease phenotype in vitro.
Our organoid model development service focuses on creating lung organoids that faithfully recapitulate the alveolar structure and functionality. By utilizing iPSCs or adult stem cells, we can generate alveolar organoids that closely resemble the cellular composition and functional properties of the lung.
In addition to the diverse range of services and models previously mentioned, our organization possesses a remarkable ability to craft bespoke solutions and develop disease models that are meticulously designed to align with your unique needs. We take great pride in our ability to adapt and customize our offerings, ensuring that they precisely cater to the specific requirements of each individual client. If our comprehensive suite of services has sparked your interest, we wholeheartedly encourage you to connect with us without any hesitation.
