Retina
The research team is led by Professor Anders Kvanta and Dr Helder André, with a research portfolio to provide unpreceded cellular and molecular mechanistic views on neovascular and degenerative retinal diseases, with high focus on translational sustainable therapy strategies for patients with blinding diseases.
The Kvanta/André group conducts translational studies focused on identifying and improving treatments of several retinal diseases, including retinal degenerations, retinal vein occlusion and diabetic retinopathy. The key area of our current research is age-related macular degeneration (AMD), one of the most common and rapidly increasing sight-threatening diseases. Advanced AMD is a major cause of severe central vision loss affecting more than 180 million people globally (over 100,000 in Sweden). Despite a seemingly low incidence, AMD has one the of fastest rates of increased prevalence in the developed world as a consequence of an aging population, and is estimated to become an immense burden for healthcare systems worldwide, with massive economic implications. Due to the protracted nature of AMD, the multifactorial mechanisms involved, and current therapeutic limitations there is a great need for long-term therapies that can regenerate lost retinal cells or mitigate multiple angiogenic and inflammatory factors known to be associated with AMD, simultaneously allowing for sustainable treatments.

Research Projects
The common goal of the Kvanta/André Lab is to develop new treatments for neovascular and degenerative retinal disease. Our experimental projects include molecular and cell biology studies, and preclinical animal models aimed to identify new molecules and pathways relevant to the onset of neovascularization and cell death for these retinal conditions. In addition, preclinical studies are ongoing with gene therapy to treat vascular retinal diseases. Our previous and ongoing research has contributed to the successful development of break-through treatments for wet (neovascular) AMD and has laid the ground for regenerative treatment of dry (degenerative) AMD using human embryonic stem cell (hESC)-derived retinal pigment epithelial cells (RPE).
