Background: Mutations in the ATP13A2 gene have been implicated in various neurodegenerative disorders, including Kufor-Rakeb syndrome (KRS), neuronal ceroid lipofuscinosis (NCL), hereditary spastic paraplegia (HSP), and amyotrophic lateral sclerosis (ALS). This report presents two Iranian families with ATP13A2 variants exhibiting atypical features of KRS.
Cases: We highlight four patients from two consanguineous Iranian families with mutations in the ATP13A2 gene presenting with variable features of motor neuron disease as well as juvenile-onset parkinsonism, and cognitive decline. The onset of symptoms ranged from 11 to 29 years, with initial manifestations including gait disturbance, postural instability, and cognitive impairment. As the disease progressed, patients developed a range of neurological signs, such as dystonia, spasticity, and dysarthria.
Conclusion: This report expands the phenotypic spectrum of ATP13A2-related disorders, highlighting the potential overlap of symptoms associated with KRS, ALS, and HSP.

Amyotrophic lateral sclerosis (ALS) is a non-neuron-autonomous disease where peripheral immune dysregulation significantly impacts disease progression. However, the immunopathological mechanisms of natural killer (NK) cells in ALS remain largely unexplored. This study enrolled 241 ALS patients and 102 healthy controls (HC), analyzing lymphocyte subsets, including T cells, B cells, and NK cells.

Amyotrophic lateral sclerosis (ALS) is categorized into ~10% familial and ~90% sporadic cases. While familial ALS is caused by mutations in many genes of diverse functions, the underlying pathogenic mechanisms of ALS, especially in sporadic ALS (sALS), are largely unknown. Notably, about half of the cases with sALS showed defects in mitochondrial respiratory complex IV (CIV).

Motor axon regeneration after traumatic nerve injuries is a slow process that adversely influences patient outcomes because muscle reinnervation delays result in irreversible muscle atrophy and suboptimal axon regeneration. This advocates for investigating methods to accelerate motor axon growth. Electrical nerve stimulation and exercise both enhance motor axon regeneration in rodents and patients, but these interventions cannot always be easily implemented.

Cadmium (Cd), a neurotoxic metal, is associated with the development of neurological disorders. This study investigated the neuroprotective effects of Luteolin against Cd-induced toxicity in cultured cells and mouse models. Our findings demonstrate that Luteolin protects hippocampal neurons from Cd toxicity and mitigates Cd-triggered inflammatory responses in microglial BV2 cells.

Nerve transfer surgery (NTS) shows promise in restoring movement to muscles paralyzed by spinal cord (SCI) and peripheral nerve injury (PNI). Yet, motor outcomes vary, and the neurophysiological factors influencing responders and non-responders remain unclear. As the fundamental goal of NTS is to reinnervate paralyzed muscles by creating new motor units (MUs), we examined MU properties after NTS for individuals with SCI and PNI.
