Neurobiologists identify widely used assembling and stabilizing forces behind brain synapses

Scientists at the University of California San Diego have discovered that planar cell polarity is a widely used mechanism for forming and maintaining glutamatergic synapses. The study found that Prickle protein plays a crucial role in stabilizing these synapses, which are essential for neuronal communication.

Polarized cells give the heart its fully developed form

Researchers have discovered how polarized cells coordinate heart tube remodelling through tissue-scale polarisation of actomyosin activity. A disrupted PCP signalling pathway alters cytoskeleton structure, leading to impaired heart formation and most congenital heart diseases.
