If a cell loses contact and leaves the microenvironment, a special type of programmed cell death is triggered, which is called <em>anoikis, <\/em>meaning homelessness in Greek. Anoikis is particularly important in case of the continuous cell division of stem cells, because in case of tumour metastases tumour cells are able to escape the process of anoikis. The researchers studied how healthy cells that have to migrate far away from the place of their formation after cell division avoid this process. In addition, accidental or environmental effects, such as cell division and migration defects caused by maternal alcohol consumption, are inevitable in the developing brain. Their hypothesis was that there must be a defence mechanism in the developing brain that prevents the dividing neural stem cells from being misplaced and forming defective cell clusters or tumours by further division.<\/p>\n<p>Zs\u00f3fia L\u00e1szl\u00f3 and Dr. Zsolt Lele proved the phenomenon of developmental anoikis by a model developed by them and discovered the enzyme ABHD4, a protein of previously unknown function, as a key element of the process. They revealed that developmental anoikis linked to the enzyme is essential for cell death in the fetal brain caused by maternal alcohol consumption. Thus, their results greatly contribute to the understanding of microcephaly, a structural impairment of fetal alcohol syndrome. According to official critics, the study published in <em>Nature Communications<\/em> is a new concept in developmental neurobiology and opens up new horizons in the research of neuron formation.<\/p>\n<p>Zs\u00f3fia L\u00e1szl\u00f3 studied at Neuromorphology and Cellular Biology Programme of Semmelweis University\u2019s Doctoral School of Neurology.
