Accumulating evidence suggests that both intrinsic and extrinsic factors shape the function of neural circuits within specific substructures of the adult brain. A primary goal of my laboratory is to identify mechanisms by which influences outside the CNS 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 immune system. As such, another arm of the laboratory will focus on characterizing the extent to which blood-borne factors altered in the course of normal aging 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 a new frontier in neuroscience: how the brain’s learning and memory (formation, consolidation) circuits are shaped by systemic influences and the extent to which this plays a role in disease.

Our Work in the News
You leave your car in a vast, crowded parking lot, and when you return, you have no idea where it is. The ensuing search is frustrating, time-consuming and a little embarrassing.
That experience occurs more frequently as we get older, because the functions of the part of the brain that encodes spatial and episodic memories — the hippocampus — decline with age.
Blood from human infants appears to improve learning and memory in older mice, a new study shows. The research is the latest in a new field of inquiry, where scientists are looking to see if blood from the very young can rejuvenate the old.
A new study hints that young blood may harbor clues to a “fountain of youth” for older brains.
Researchers say blood from human umbilical cords appears to have helped reverse memory loss in aging mice.
The findings suggest that something in young blood is important in maintaining mental acuity.
Decades ago, scientists surgically attached pairs of rats to each other and noticed that old rats tended to live longer if they shared a bloodstream with young rats.
It was the beginning of a peculiar and ambitious scientific endeavor to understand how certain materials from young bodies, when transplanted into older ones, can sometimes improve or rejuvenate them.
Dementia patients have been offered hope that their memory could be repaired after scientists showed that injecting blood from the umbilical cords of human babies restores brain function.
How do blood-borne factors influence the brain in the context of disease?
Conventional wisdom has held that the blood-brain barrier isolates the brain from the influence of the immune system and systemic environment. 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).
By 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 TIMP 2 using antibody-mediated approaches or through genetic ablation results in profound alterations in spatial memory in adult mice. While TIMP2-expressing hilar neurons are present at high levels 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.

Joseph Castellano, Ph.D.
Role: Principal Investigator
As a graduate student in David Holtzman’s group at Washington University in St. Louis, I studied how the strongest genetic risk factor for Alzheimer’s disease influences metabolism of the pathogenic amyloid beta peptide from brain interstitial fluid. I used in vivo microdialysis to show in behaving mice that clearance of this peptide is impeded by the presence of APOE4 whereas clearance in the context of more protective forms is faster. During my postdoctoral training in Tony Wyss-Coray’s group at Stanford University, I became engrossed in characterizing factors in the periphery that reverse features of brain aging, finding that systemic umbilical cord plasma treatment revitalizes hippocampal function in aged mice. My laboratory now focuses on characterizing the activity of blood-borne proteins like TIMP2 that mediate long-range effects on circuits in the brain in the context of Alzheimer’s disease.
Ana Catarina Ferreira
Role: Postdoctoral Fellow
Catarina received her PhD in Health Sciences in 2017 from the School of Medicine at the University of Minho in Portugal. During this time, she focused on the identification of novel mechanisms that regulate different forms of neural plasticity, specifically the generation of new neural cells in the adult brain and the implications of this plasticity in the overall maintenance of brain homeostasis and behavior. Catarina demonstrated that the iron-traffic protein lipocalin-2 (LCN2) is required to control quiescent and active states of adult neural stem cells for proper adult cell genesis, ultimately regulating cognitive function. As a postdoc in the Castellano lab, Catarina is focused on understanding how activity of the youth-associated blood-born factor TIMP2 shapes brain circuits linked to learning and memory and understanding this action in the context of Alzheimer’s disease. Outside the lab, Catarina enjoys reading, spending time with friends, and traveling.
Role: Postdoctoral Fellow
Monika received her PhD in Neurosciences in 2019 from the Indian Institute of Science. During graduation, she explored the molecular mechanisms leading to generation of neuroprotective astrocytes. She showed that deletion of serum response factor in an astrocyte-specific manner leads to conversion of normal astrocytes into reactive astrocytes. She further demonstrated that these reactive astrocytes are of neuroprotective subtype which confer neuroprotection against neural injuries and kainite-induced seizures. Outside the lab, Monika enjoys travelling, sketching, dancing and exploring new restaurants.
Role: Associate Researcher
Hanxiao Liu graduated from Teachers College Columbia University with a MA in Clinical Psychology. He worked in the Veenstra-VanderWeele lab as a volunteer during his graduate years, participating in the study of the balance between the hippocampus and the striatum and the impact of maternal serotonin system on the developing brain. In the Castellano Lab, he wishes to learn more about hippocampal function and how it can be altered by Alzheimer’s Disease. In his free time, Hanxiao enjoys hiking and showtunes.
Role: PhD Student
Brittany received her B.S. in Biology, B.A. in Psychology, and Neuroscience Certificate from Providence College in 2017. As an undergraduate, Brittany spent 3 years in the Neuroscience and Animal Cognition laboratory studying the effects of aging and social housing on learning and memory. After graduation, to explore her burgeoning interest in neuroimmunology, she worked in the Laboratory for Aging Neuroscience at Brigham and Women’s Hospital and examined the neurobiological and immunological basis of memory dysfunction in the aged brain following anesthesia and surgery. As a PhD student and current T32 fellow in the Castellano lab, Brittany aims to elucidate how blood-borne factors influence glial cells to shape brain aging and affect the development of neurodegenerative diseases like Alzheimer’s disease. Outside of research, Brittany enjoys participating in neuroscience outreach, traveling with friends, and scuba diving (when the opportunity arises)
Role: PhD Student
Sarah received her B.S. in Cellular & Molecular Biology, Psychology, and minor in Chemistry from the University of Wisconsin-Milwaukee (UWM) in 2019. From 2016-2020, Sarah worked in Dr. Karyn Frick’s Neuroendocrinology of Memory Lab where she studied the neurobiology of learning and memory using sex-steroid hormones in mouse models of menopause and Alzheimer’s disease pathology. During this time, she contributed to work investigating the influence of sex, APOE genotype, and 17β-estradiol on behavioral and molecular phenotypes in EFAD-tg mice. As a graduate student in the Castellano lab, Sarah’s primary research interests involve investigating peripheral factors that may be protective, or deleterious, in normal aging and Alzheimer’s disease. When she’s not in the lab, Sarah is most likely exploring New York’s restaurant scene with friends or practicing her embroidery.
Role: Medical Resident
Phil received his MD/PhD in 2020 from Icahn School of Medicine at Mount Sinai. He worked with Dr. Matthew Shapiro for his dissertation on flexible rodent learning in dorsal and ventral hippocampus. He is now a Neurology resident at ISMMS and is learning computational methods to evaluate differential gene expression in mouse models of aging.
Role: Masters Student
Yihang received her B.S. in biology in 2018 from Wuhan University in China. During her undergraduate years, her study focused on conducting mouse surgeries to identify the neurocircuits associated with the hippocampus using different types of virus vectors. Her bachelor thesis is around identifying the monosynaptic input of the excitatory neurons of the amygdala on a whole-brain basis. As a new masters student here at Mount Sinai, her interest is to take what she learned before and direct it in a way that’s more focused on neurodegenerative diseases like Alzheimer’s. Apart from scientific research, she also enjoys exploring New York’s numerous museums and Broadway shows and reading a good book with her cat Dulcinea purring on the lap.
Role: Undergraduate Research Assistant
Jake is a rising senior at Georgetown University working towards a B.S. in Neurobiology. He was first introduced to research on Alzheimer’s Disease, and APOE in particular, as a freshman, when he wrote a paper on the intersection of genetic and environmental factors in contributing to AD. At Georgetown, Jake works in Dr. Sarah Flowers’ Lab within the School of Medicine’s Department of Neuroscience, where he studies how the allelic variants of APOE influence microglial and astrocytic function. In the Castellano Lab, Jake is interested in the effect of TIMP2 on amyloid plaque, the buildup of which is considered a hallmark of AD. He is enjoying translating his previous experience in cell culture into work with animal-based models. Outside of the lab, Jake enjoys playing the piano and watching the New York Jets.
Role: Undergraduate Research Assistant
Julia is currently a senior at Fordham University at Lincoln Center, where she is working toward a B.S. in Integrative Neuroscience with a concentration in Cell and Molecular Neuroscience. As an undergraduate research intern in the Castellano Laboratory, she hopes to further develop her laboratory skills and deepen her understanding of neuroimmunology and neurodegenerative diseases. After graduation, she plans to pursue a PhD in Neuroscience and become a research scientist in the field. Julia’s outside interests include yoga, hiking, and playing guitar.
