Abstract

Two hundred and fourteen normal offspring from 45 litters of mice were studied. Daily examinations employing a spectrum of reflexologic tests as indicators of neurologic development were followed from birth to 4 weeks of age. Five periods of neurologic development were found, each period having reflex responses characteristic of the behaviour and neurologic development of that age. The periods were designatedperinatal (birth to 3 days),neonatal (3 to 9 days),postnatal transition (9 to 15 days),postnatal infantile orpre-juvenile (15 to 26 days), andjuvenile (from 26 days until sexual maturity). These findings were correlated with data from previous studies, and it was confirmed that the end of the Postnatal transition period is the most critical period of development, when all aspects of neural maturation suddenly reach adultlike perfection. It was concluded that reflex tests are useful in assessing the degree of neural maturation in the developing mouse, and are reliable indicators of normal development.

No significant sex differences in incidence or phenotype for the SMNΔ7 mouse model of spinal muscular atrophy
2024, Neuromuscular Disorders
Spinal muscular atrophy (SMA) is an autosomal recessive disease that affects 1 out of every 6,000-10,000 individuals at birth, making it the leading genetic cause of infant mortality. In recent years, reports of sex differences in SMA patients have become noticeable. The SMNΔ7 mouse model is commonly used to investigate pathologies and treatments in SMA. However, studies on sex as a contributing biological variable are few and dated. Here, we rigorously investigated the effect of sex on a series of characteristics in SMA mice of the SMNΔ7 model. Incidence and lifespan of 23 mouse litters were tracked and phenotypic assessments were performed at 2-day intervals starting at postnatal day 6 for every pup until the death of the SMA pup(s) in each litter. Brain weights were also collected post-mortem. We found that male and female SMA incidence does not differ significantly, survival periods are the same across sexes, and there was no phenotypic difference between male and female SMA pups, other than for females exhibiting lesser body weights at early ages. Overall, this study ensures that sex is not a biological variable that contributes to the incidence ratio or disease severity in the SMNΔ7 mouse model.
Early movement restriction affects the acquisition of neurodevelopmental reflexes in rat pups
2024, Brain Research
Childhood is a period of construction of the organism, during which interactions with the environment and regular physical activity are necessary for the maturation of the neuronal networks. An atypical sensorimotor activity during childhood (due to bed-rest or neurodevelopmental disorders) impacts the development of the neuromuscular system. A model of sensorimotor restriction (SMR) developed in rats has shown that casting pups’ hind limbs from postnatal day 1 (P1) to P28 induced a severe perturbation of motor behavior, due to muscle weakness as well as disturbances within the central nervous system. In the present study, our objective was to determine whether SMR affects the early postnatal ontogenesis. We explored the neuromuscular development through the determination of the age for achievement of the main neurodevelopmental reflexes, which represent reliable indicators of neurological and behavioral development. We also evaluated the maturation of postural control. Our results demonstrate that SMR induces a delay in the motor development, illustrated by a several days delay in the acquisition of a mature posture and in the acquisition reflexes: hind limb grasping, righting, hind limb placing, cliff avoidance, negative geotaxis. In conclusion, impaired physical activity and low interactions with environment during early development result in altered maturation of the nervous system.
Preventive effects of resveratrol against early-life impairments in the animal model of autism induced by valproic acid
2023, IBRO Neuroscience Reports
Autism Spectrum Disorder (ASD) is a neurodevelopmental condition characterized by social interaction deficits and repetitive/stereotyped behaviors. Its prevalence is increasing, affecting one in 36 children in the United States. The valproic acid (VPA) induced animal model of ASD is a reliable method for investigating cellular, molecular, and behavioral aspects related to the disorder. Trans-Resveratrol (RSV), a polyphenol with anti-inflammatory and antioxidant effects studied in various diseases, has recently demonstrated the ability to prevent cellular, molecular, sensory, and social deficits in the VPA model. In this study, we examined the effects of prenatal exposure to VPA and the potential preventive effects of RSV on the offspring.
We monitored gestational weight from embryonic day 6.5 until 18.5 and assessed the onset of developmental milestones and morphometric parameters in litters. The generalized estimating equations (GEE) were used to analyze longitudinal data.
Exposure to VPA during rat pregnancy resulted in abnormal weight gain fold-changes on embryonic days 13.5 and 18.5, followed by fewer animals per litter. Additionally, we discovered a positive correlation between weight variation during E15.5-E18.5 and the number of rat pups in the VPA group.
VPA exposure led to slight length deficiencies and delays in the onset of developmental milestones. Interestingly, the prenatal RSV treatment not only prevented most of these delays but also led to the early onset of certain milestones and improved morphometric characteristics in the offspring. In summary, our findings suggest that RSV may have potential as a therapeutic intervention to protect against the negative effects of prenatal VPA exposure, highlighting its importance in future studies of prenatal neurodevelopmental disorders.
Early postnatal development of the MDGA2<sup>+/-</sup> mouse model of synaptic dysfunction
2023, Behavioural Brain Research
Synaptic dysfunction underlies many neurodevelopmental disorders (NDDs). The membrane-associated mucin domain-containing glycosylphosphatidylinositol anchor proteins (MDGAs) regulate synaptic development by modulating neurexin–neuroligin complex formation. Since understanding the neurodevelopmental profile and the sex-based differences in the manifestation of the symptoms of NDDs is important for their early diagnosis, we tested a mouse model haploinsufficient for MDGA2 (MDGA2^+/-) on a neurodevelopmental test battery, containing sensory, motor, and cognitive measures, as well as ultrasonic vocalizations. When male and female MDGA2^+/- and wildtype (WT) C57BL/6 J mice were examined from 2 to 23 days of age using this test battery, genotype and sex differences in body weight, sensory-motor processes, and ultrasonic vocalizations were observed. The auditory startle reflex appeared earlier in the MDGA2^+/- than in WT mice and the MDGA2^+/- mice produced fewer ultrasonic vocalizations. The MDGA2^+/- mice showed reduced locomotion and rearing than WT mice in the open field after 17 days of age and spent less time investigating a novel object than WT mice at 21 days of age. Female MDGA2^+/- mice weighed less than WT females and showed lower grip strength, indicating a delay in sensory-motor development in MDGA2^+/- mice, which appears to be more pronounced in females than males. The behavioural phenotypes resulting from MDGA2 haploinsufficiency suggests that it shows delayed development of motor behaviour, grip strength and exploratory behaviour, non-social phenotypes of NDDs.
Alternative splicing and heparan sulfation converge on neurexin-1 to control glutamatergic transmission and autism-related behaviors
2023, Cell Reports
Neurexin synaptic organizing proteins are central to a genetic risk pathway in neuropsychiatric disorders. Neurexins also exemplify molecular diversity in the brain, with over a thousand alternatively spliced forms and further structural heterogeneity contributed by heparan sulfate glycan modification. Yet, interactions between these modes of post-transcriptional and post-translational modification have not been studied. We reveal that these regulatory modes converge on neurexin-1 splice site 5 (S5): the S5 insert increases the number of heparan sulfate chains. This is associated with reduced neurexin-1 protein level and reduced glutamatergic neurotransmitter release. Exclusion of neurexin-1 S5 in mice boosts neurotransmission without altering the AMPA/NMDA ratio and shifts communication and repetitive behavior away from phenotypes associated with autism spectrum disorders. Thus, neurexin-1 S5 acts as a synaptic rheostat to impact behavior through the intersection of RNA processing and glycobiology. These findings position NRXN1 S5 as a potential therapeutic target to restore function in neuropsychiatric disorders.
Delayed postnatal brain development and ontogenesis of behavior and cognition in a mouse model of intellectual disability
2023, Neurobiology of Disease
Intellectual disability (ID) is a neurodevelopmental disorder associated with impaired cognitive and adaptive behaviors and represents a major medical issue. Although ID-patients develop behavioral problems and are diagnosed during childhood, most behavioral studies in rodent models have been conducted in adulthood, missing precocious phenotypes expressed during this critical time-window characterized by intense brain plasticity. Here, we selectively assessed postnatal ontogenesis of behavioral and cognitive processes, as well as postnatal brain development in the male Rsk2-knockout mouse model of the Coffin-Lowry syndrome, an X-linked disorder characterized by ID and neurological abnormalities. While Rsk2-knockout mice were born healthy, a longitudinal MRI study revealed a transient secondary microcephaly and a persistent reduction of hippocampal and cerebellar volumes. Specific behavioral parameters from postnatal day 4 (P4) unveiled delayed acquisition of sensory-motor functions and alterations of spontaneous and cognitive behaviors during adolescence, which together, represent hallmarks of neurodevelopmental disorders. Together, our results suggest for the first time that RSK2, an effector of the MAPK signaling pathways, plays a crucial role in brain and cognitive postnatal development. This study also provides new relevant measures to characterize postnatal cognitive development of mouse models of ID and to design early therapeutic approaches.
