How The Brain Develops – Indian Scientist Develops New Study Model

    Yogita K. Adlakha, an Indian Scientist and a recipient of INSPIRE Faculty fellowship instituted by the Department of Science and Technology (DST), has developed human-based models to study neuron development and neuro-developmental disorders such as autism which can help design treatment strategies for such brain disorders.

    Yogita Adlakha, a recipient of INSPIRE Faculty fellowship instituted by the Department of Science and Technology (DST), has achieved this feat, the DST said on Wednesday.

    INSPIRE — is a scheme by the DST for attracting talent towards science

    Over several years, animal models have been used to understand brain-related disorders, and the drugs which function in animal models have failed in clinical trials, therefore Adlakha filled this gap by generating human-based stem cell model to understand brain development and dysfunction at the National Brain Research Centre, Manesar, Haryana.

    The study provides first evidence that a brain enriched miRNA-137 induces neuronal differentiation and inhibits proliferation using human neural stem cells derived from induced pluripotent stem cells (iPSCs).

    At present, she works as a scientist at the Translational Health Science and Technology Institute, NCR Bio-cluster, Faridabad.

    “The dearth of human models has led to a lack of knowledge of the pathophysiology of such disorders, an essential requirement for designing their treatment strategies,” the DST said.

    “My research using DST INSPIRE fund has definitely contributed to expanding the knowledge of neuron development and neuro-developmental disorders such as autism and the role of small non-coding miRNA in brain-specific stem cells fate,” Adlakha added.

    Yogita filled this gap and developed a human-based model that could help study how brain develops, particularly the neurons, and what goes awry during brain development leading to cognitive decline, impairment in language, and social interaction.

    Along with her group, she derived induced pluripotent stem cells (iPSCs) from human peripheral blood and differentiated them into neural stem cells (NSCs).

    Since levels of microRNA-137 are less in neuro-developmental disorders such as ASD and ID, her study demonstrates crucial roles of this miRNA during human NSC fate determination with an elaboration of underlying molecular mechanisms. This study was published in the journal “STEM CELLS” recently.

    Along with her research group, she established a protocol from India for the first time by generating and producing iPSCs from human peripheral blood. They have further refined the protocol of differentiation of iPSCs into brain-specific stem cells that is, NSCs.
