Adult CNS neurons are typically described as permanently postmitotic but there is probably nothing permanent about the neuronal cell cycle arrest. Rather, it appears that these highly differentiated cells must constantly keep their cell cycle in check. Relaxation of this vigilance leads to the initiation of a cell cycle and entrance into an altered and vulnerable state, often leading to death. There is evidence that neurons which are at risk of neurodegeneration are also at risk of re… 

Cell Cycle Re-entry in the Nervous System: From Polyploidy to Neurodegeneration

The potential functions of polyploidization in the nervous system, particularly in the context of long-lived cells and age-associated polyploids, are discussed and an attempt is made to reconcile the seemingly disparate associations of neuronalpolyploidy with both neurodegeneration and neuroprotection.

Core cell cycle machinery is crucially involved in both life and death of post-mitotic neurons

This review aims at summarizing current knowledge about the role of the cell cycle machinery in post-mitotic neurons in healthy and pathological conditions.

Cell cycle and cell fate in the developing nervous system: the role of CDC25B phosphatase

Recent data are summarized describing how cell cycle dynamics affect the switch between proliferation and differentiation, with an emphasis on the roles played by the cell cycle regulators, the CDC25 phosphatases.

Scratch2 Prevents Cell Cycle Re-Entry by Repressing miR-25 in Postmitotic Primary Neurons

It is shown that Scratch2 is involved in the control of the cell cycle in neurons in the developing spinal cord of the zebrafish embryo and appears to safeguard the homeostasis of postmitotic primary neurons by preventing cell cycle re-entry.

Cell Cycle Activation and CNS Injury

Treatments that inhibit cell cycle may have robust neuroprotective profiles, particularly after acute insults, by targeting multiple pathogenic mechanisms and could be useful clinically if used with a delivery focused on specific areas and of a limited duration.

Mitotic biology of primary neurons

In conclusion, neurons and mitotic cells share G1, S, G2 and M-phase regulation and are capable of undergoing cell division.

Amitosenescence and Pseudomitosenescence: Putative New Players in the Aging Process

A revision of the current view on the process and definition of senescence is proposed by encompassing a primarily replication-incompetent state (amitosenescence), which might be expanded by events of atypical cell cycle activity (pseudomit Rosenescence).

E2F1 Works as a Cell Cycle Suppressor in Mature Neurons

The results suggest that, in mature CNS neurons, E2F1 functions as a cell cycle suppressor.

In Vivo Viability of Postmitotic Purkinje Neurons Requires pRb Family Member Function

It is described that T-ag expression induces DNA synthesis and results in DNA fragmentation in Purkinje neurons and indicates that a pRb function is required well beyond the completion of Purkinjen neuron differentiation and provides a link between cell cycle regulation and neurodegeneration in vivo.

The induction of multiple cell cycle events precedes target-related neuronal death.

The data indicate that target-related cell death in the developing central nervous system is associated with a mechanism of cell death that involves an apparent loss of cell cycle control.
