abstract = {In mammalian axon-carrying–dendrite (AcD) neurons, the
axon emanates from a basal dendrite, instead of the soma, to
create a privileged route for action potential generation at
the axon initial segment (AIS). However, it is unclear how
such unusual morphology is established and whether the
structure and function of the AIS in AcD neurons are
preserved. By using dissociated hippocampal cultures as a
model, we show that the development of AcD morphology can
occur prior to synaptogenesis and independently of the in
vivo environment. A single precursor neurite first gives
rise to the axon and then to the AcD. The AIS possesses a
similar cytoskeletal architecture as the soma-derived AIS
and similarly functions as a trafficking barrier to retain
axon-specific molecular composition. However, it does not
undergo homeostatic plasticity, contains lesser cisternal
organelles, and receives fewer inhibitory inputs. Our
findings reveal insights into AcD neuron biology and
underscore AIS structural differences based on axon onset.},
