Claudia Molina is currently a Research Associate in Professors Uta Griesenbach and Eric Alton’s Gene Therapy Group at the National Heart and Lung Institute. She joined the group in 2019 after a 5 year position as a Researcher in industry, where she worked in Adult Mesenchymal Stem Cell Therapies for the treatment of degenerative and autoimmune diseases. Prior to this she graduated from the University of Kent with a BSc in Molecular and Cellular Biology, and was then awarded a MSc in Molecular Medicine from the University College London and finally a PhD from the University of Oxford in HIV immunology.

Her earlier work investigated the evolution of the Human Immunodeficiency Virus (HIV) within an individual and at a population level, the aim was to try to understand the mechanisms by which certain HLA class I alleles and CTL responses restricted by those alleles are associated with effective or ineffective control of HIV. Her work suggested that antiretroviral therapy (ART) treatment-for-prevention strategies will be less successful in populations such as those in Mexico, where viral loads are higher for a given CD4 T cell count. Consideration may therefore usefully be given to ART initiation at higher absolute CD4 T cell counts in such populations to optimize the impact of ART for prevention. She was recognized as a member of the National system of Researchers in Mexico in 2015.

Her current work revolves around the design and testing of gene therapies for the treatment of autoimmune Pulmonary Alveolar Proteinosis (aPAP). aPAP is a rare genetic lung disease caused by auto-antibodies against GM-CSF leading to defective surfactant clearance. Accumulation of extracellular surfactants leads to decreased gas exchange. Standard of care for aPAP is the removal of excess surfactants by whole lung lavage (WLL), a procedure which is very demanding, particularly in children and can only be performed at specialised centres, involves prolonged anaesthesia and often requires ventilation in intensive care units. The impact of a new advanced therapeutics treatment for the disease may be significant. The UKCF Gene Therapy Consortium generated a patent-protected novel lentiviral vector pseudotyped with the F/HN proteins from Sendai virus (rSIV.F/HN) specifically designed to achieve high efficiency targeting the lung. This vector is currently being tested for the expression of GM-CSF as a method of treatment for aPAP.
