Research Summary

Research in the Oliveros Lab studies Regenerative Neurobiology in disease states that detrimentally affect cognitive function and reward motivated behavior. Although advancements in cancer treatment has significantly increased survivability, chemotherapy related cognitive impairment, colloquially known as chemobrain or chemofog, has emerged as a significant off-target effect that can negatively affect up to 75% of cancer survivors. Unfortunately, there are no current treatments to alleviate this condition, which is typified by dysfunctions in cognition and mood, in conjunction with impaired neural stem cell development (i.e., neurogenesis) and neuroinflammation. Therefore, elucidation of novel treatment strategies is of paramount importance to improve quality of life for cancer survivors,

By employing a multidisciplinary approach that includes preclinical mouse models of behavior, pharmacology, RNA sequencing, proteomics, bioinformatic pathway analysis, brain region specific viral mediated (AAV-Cre) stereotaxic targeting, molecular biology, cell-type specific assessment and immunofluorescence/confocal microscopy, the Oliveros Lab is actively investigating the molecular mechanisms by which different classes of chemotherapies disrupt hippocampal and striatal function, resulting in impaired memory, attention, and emotive behavior.

Ongoing projects in the Oliveros Lab include:

1. Investigating how cancer and chemotherapy impair neurogenesis to contribute to learning, memory, and emotive dysfunctions.
The Oliveros Lab investigates colocalized expression of the cellular proliferation marker MCM2 and the immature neuroblast marker DCX along the subgranular zone of the dentate gyrus in the mouse hippocampus, a brain region known as a neurogenic niche that controls memory processes and emotive behavior. To study these neurobiological processes, the Oliveros lab routinely employs complex behavior memory assays including the Morris water maze and Novel Object Recognition, the elevated plus maze to test anxiety-like behavior, as well as operant conditioning techniques to study attention, such as pattern separation and the 5-choice serial reaction time task (5-CSRTT).

2. Exploring how cancer and chemotherapy activates immunity to detrimentally affect cognitive function
To assess how neuroinflammatory processes during chemobrain may detrimentally affect cognition, the Oliveros Lab studies activation states of microglia in multiple brain regions, including the hippocampus, cortex, and striatum. In addition, the Oliveros Lab investigates innate and adaptive immune cell populations in the meningeal compartment of the mouse to determine how these cell populations contribute to cognitive dysfunction in chemobrain.
