Researchers have been investigating the potential of innovative cognitive impairment medicine, and recently, a novel experimental therapeutic agent has emerged.
Although it’s a cancer drug, this agent, known as ADH-503, has shown promise in addressing cognitive challenges associated with Rett syndrome—a rare neurological condition linked to autism.
The drug has been observed to enhance synaptic connectivity and promote neuroplasticity, potentially counteracting the cognitive deficits commonly experienced by Rett syndrome.
This study refers to this medicine and specifically emphasizes the pivotal involvement of microglia, a specialized category of leukocytes situated within the central nervous system, in the developmental processes of the human brain. It found that the drug increased the activation of healthy microglia, facilitating the restoration of synaptic integrity within brain organoids that simulate the characteristics of Rett syndrome.
According to Dr. Mesci, an esteemed researcher in the field, it’s not the first time the importance of microglial function has been highlighted in neurological research. Still, this study further delineates their crucial role in the context of Rett syndrome.
The procedure
Mesci and her team sampled skin stem cells from individuals with Rett syndrome and closely replicated the intricate development processes of the brain organoids during embryogenesis in a controlled laboratory environment. This allowed them to compare the organoids derived from patients with Rett syndrome to those sourced from neurotypical individuals.
For those unfamiliar with Rett syndrome, it’s another neurodevelopmental disorder that predominantly affects females and is characterized by a significant regression in cognitive and physical abilities. Symptoms typically emerge in the first two years of life and may include a loss of purposeful hand skills, speech difficulties, and mobility challenges.
The nuanced differences in brain organoids derived from individuals with Rett syndrome compared to neurotypical counterparts were hoped to provide researchers with invaluable insights. Mesci furthered the research by incorporating healthy microglia into the Rett syndrome brain organoids.
The research findings.
The results revealed that introducing Rett syndrome microglia affected neuron synapse functionality. This was notably linked to the restoration of phagocytosis, allowing microglia to clear away debris and support neuronal health effectively. Professor Muotri, head of the Integrated Space Stem Cell Orbital Research Center, emphasized that understanding the role of microglia in Rett syndrome is crucial for future therapeutic strategies.
When faulty microglia are present, the cognitive challenges faced by Rett syndrome patients could worsen, highlighting the importance of targeted research.
