Ageing & Tissue Repair – Immune Modulation in Tissue Repair
A central goal of regenerative medicine is the ability to restore or rejuvenate tissues using stem cells. This approach relies on harnessing repair processes that have evolved to heal damaged tissues and to maintain tissue homeostasis. Immune modulation is an integral part of the process of tissue repair, and dysregulated immune responses are likely contributors to tissue dysfunction observed in old individuals. Age-associated inflammation, in particular, is likely an important roadblock for the success of regenerative therapies in ageing. Thus, immune modulation aimed towards harnessing the anti-inflammatory function of immune cells to promote endogenous repair mechanisms is a promising strategy to improve regenerative success in older individuals.
In the Neves Lab we use skeletal muscle regeneration as a paradigm of tissue repair to understand the molecular and cellular basis of the immune modulatory component of tissue regeneration and how its dysregulation in ageing and disease can be targeted to optimize regenerative success. Our goal is to identify pathways that are used by immune cells to modulate the inflammatory tone of the tissue environment, with the goal of identifying new molecules with immune modulatory properties and therapeutic potential in regenerative medicine applied to old patients.
The Neves Lab is part of the Ageing & Tissue Repair joint lab, running two independent, complementary and cooperative research programs led by two group leaders: The research program in Sousa-Victor Lab aims to understand intrinsic limitations of aged stem cells. The Neves Lab is focused on inflammatory signaling in ageing and immune modulatory strategies to improve regenerative success. Our goal is to apply the insights from the study of alterations in the ageing immune environment and stem cell ageing to develop new stem cell-based therapies to improve the health of old individuals. By studying stem cell function and immune modulatory mechanisms in an integrated manner, rather than as independent problems in the biology of tissue repair, we aim to provide a better understanding of the problems and optimized strategies for stem-cell based therapies in aging.
The Ageing & Tissue Repair joint lab uses Drosophila and in vitro models as platforms for screening, discovery and mechanistic studies, which are then translated into functional studies using mouse models and validated in human samples.
