The research interests of the Angiogenesis Lab are focused on cardiovascular biology, mainly on the study of molecular mechanisms governing physiological and pathological angiogenesis, and on drug discovery devoted to inhibit pathological angiogenesis.

Biochemical and functional relationship of molecular factors involved in angiogenesis are studied using molecular and cellular biology approaches and functional genomics in mice.

Moreover, for these studies is crucial the availability at Angiogenesis Lab of in vivo disease models, such as syngeneic and xenograft tumors, corneal and choroid neovascularization, hind limb ischemia.

In the last ten years, the research activities of Angiogenesis Lab have been granted by Horizon 2020, AIRC, Telethon, government agencies (MIUR, MISE, Campania Region) and from national and foreign companies (Bayer, Abbott, Thromb-X, Multimedica, BIOVIIIx).

The studies on drug discovery has allowed the opportunity to co-found an innovative start up, named AnBition, which activities are focused on developing new molecules and technologies for treating or diagnosing angiogenesis-related diseases.

In the picture, the contribution of Angiogenesis Lab into unveil the important role of VEGF-A/PlGF heterodimer in pathological angiogenesis.
