joseph m castellano profile picAccumulating evidence suggests that both intrinsic and extrinsic factors shape the function of neural circuits within certain substructures of the adult brain. A primary goal of my laboratory is to identify mechanisms by which blood-borne factors regulate brain function in the context of aging and disease. I recently demonstrated that the youth-associated blood-borne factor tissue inhibitor of metalloproteinases 2 (TIMP2) revitalizes hippocampal synaptic plasticity and cognition in aged mice. We are now actively exploring how TIMP2 acts on circuits linked to learning and memory at molecular, morphological, and transcriptional levels of analysis. Given that TIMP2’s role in the brain is relatively unknown, we are creating a variety of genetic tools to begin probing the precise mechanism by which TIMP2 and its putative binding partners act to shape synaptic plasticity processes. A related goal of my group is to clarify the link between risk factors for neurodegenerative disease and the systemic environment. As such, another arm of the laboratory will focus on characterizing the extent to which blood-borne factors altered in the course of the normal aging process play a role in the pathogenesis of Alzheimer’s disease or other neurodegenerative disorders. We leverage both systems “big data” approaches as well as conventional molecular, cellular, and behavioral methodologies to understand how the brain’s learning and memory circuits are shaped by systemic influences in the setting of disease.

Role of Blood-borne Factors in Shaping Synaptic Plasticity in Diseases of Aging

Conventional wisdom has held that the brain is relatively isolated from the influence of the immune system and systemic environment as a result of the blood-brain barrier. The concept that neural networks have a limited capacity for repair has also been challenged by recent progress in regenerative biology. With the discovery of novel immune interactions and anatomical pathways that link the peripheral and central compartments, opportunities have emerged to investigate blood/brain communication in attempts to develop new therapeutic targets for devastating disorders of the nervous system.

Studies over the past decade have uncovered the regenerative capacity of aged tissues via factors in the blood (ref 1 for review; see Figure 1). regenerative aged tissues factors bloodBy surgically connecting young and aged mice via parabiosis, various groups working across disciplines have demonstrated that aged tissue is capable of revitalization simply by its exposure to cellular or molecular components of the young systemic milieu. Exposure to such factors via parabiosis or following transfer of young plasma revitalizes diverse processes within the brain, including vascularization, the birth of new neurons, synaptic plasticity and learning and memory (refs 1 – 4).

I recently demonstrated that human plasma from an early developmental stage–umbilical cord plasma–contains proteins capable of revitalizing spatial learning and memory while increasing synaptic plasticity (ref 5). Moreover, we found that the youth-associated blood-borne factor, tissue inhibitor of metalloproteinases 2 (TIMP2), is necessary for the cognitive benefits conferred by cord plasma in aged mice. Neutralizing systemic pools of TIMP2 using antibody-mediated approaches or through genetic ablation results in profound alterations in spatial memory in adult mice. Moreover, while TIMP2 is expressed at high levels in hilar neurons within the dentate gyrus in young mice, the number of these neurons declines profoundly with age. Systemic perturbation of TIMP2 results in functional changes at the level of synapses and, in some cases, at the level of gene transcription. A key focus of our group is to characterize how TIMP2 and related molecules act on circuits linked to learning and memory at various levels of analysis. We will answer fundamental questions of TIMP2 biology while also seeking the broader picture of how circulating molecules influence risk for disorders of the CNS and how aging shapes risk for these disorders. We will employ cutting-edge molecular and behavioral approaches to examine function while using next-generation ChIP-seq and RNA-seq approaches to unravel the complex interplay between systemic and central compartments.
