Growing evidence has indicated a potential association between maternal consumption of caffeine and impaired cognition and behavior in rodent offspring. However, potential sex differences, as well as caffeine-related effects in subsequent generations are still poorly investigated. We aimed to investigate the impact of pre-and/or neonatal exposition to caffeine on the neurodevelopment of male and female mice offspring.

Article Synopsis
  • The study examines how the Renin Angiotensin System (RAS) is involved in mild traumatic brain injury (mTBI), focusing on changes in RAS components in an animal model.
  • It found increased levels of certain RAS components in specific brain regions after injury, alongside changes in receptor expression over time.
  • Treatment with RAS-blocking medications improved motor activity and reduced anxiety in mTBI mice, suggesting potential therapeutic options for managing mTBI symptoms.

Recent evidence has supported a pathogenic role for neuroinflammation in Parkinson's disease (PD). Inflammatory response has been associated with symptoms and subtypes of PD. However, it is unclear whether immune changes are involved in the initial pathogenesis of PD, leading to the non-motor symptoms (NMS) observed in its prodromal stage.

The factor RasGEF1b is a Ras guanine exchange factor involved in immune responses. Studies have also implicated RasGEF1b in the CNS development. It is still limited the understanding of the role of RasGEF1b in CNS functioning.

The pathophysiology of post-traumatic brain injury (TBI) behavioral and cognitive changes is not fully understood, especially in its mild presentation. We designed a weight drop TBI model in mice to investigate the role of neuroinflammation in behavioral and cognitive sequelae following mild TBI. C57BL/6 mice displayed depressive-like behavior at 72 h after mild TBI compared with controls, as indicated by a decrease in the latency to first immobility and climbing time in the forced swim test.

Objective And Design: The present study aimed to investigate the neurochemical and behavioral effects of the acute consequences after coronavirus infection through a murine model.

Material: Wild-type C57BL/6 mice were infected intranasally (i.n) with the murine coronavirus 3 (MHV-3).

Article Synopsis
  • COVID-19 mainly impacts the lungs but can also cause widespread issues like muscle weakness, fatigue, and myalgia, which may worsen patient outcomes.
  • A study using C57BL/6J mice infected with a coronavirus (MHV-3) found significant motor impairment and weakness related to neuromuscular system changes.
  • The infected mice exhibited motoneuron degeneration, atrophy at the neuromuscular junction, and muscle fiber type changes, indicating that coronaviruses can disrupt motor function and muscle health.

Cocaine-induced neuroinflammation plays an important role in the pathophysiology of drug addiction. Evidence suggests that the immune response contributes for memory consolidation related to place preference behavior underlying cocaine administration in mice. Conditioned place preference (CPP) is a protocol extensively used to study the rewarding and/or aversive motivational effects of drug abuse in rodents, reproducing cocaine-seeking behavior in humans.

Traumatic brain injury (TBI) is a serious public health problem, affecting 69 million people worldwide annually. Mild TBI (mTBI) comprises the majority of the cases and remains the most neglected TBI severity. Its intricate pathophysiology involves complex cellular and molecular processes that remain uncomprehended.

Traumatic brain injury (TBI) is a serious cause of disability and death among young and adult individuals, displaying complex pathophysiology including cellular and molecular mechanisms that are not fully elucidated. Many experimental and clinical studies investigated the potential relationship between TBI and the process by which neurons are formed in the brain, known as neurogenesis. Currently, there are no available treatments for TBI's long-term consequences being the search for novel therapeutic targets, a goal of highest scientific and clinical priority.

The mechanisms involved in the maintenance of cigarette smoking and nicotine reward remain unclear. Immune response might play an important role in this context. Nicotine may induce both central and systemic inflammatory responses as well as changes in the regulation of brain-derived neurotrophic factor (BDNF).

Background: The Renin-Angiotensin System (RAS) is a key regulator of cardiovascular and renal homeostasis, but also plays important roles in mediating physiological functions in the central nervous system (CNS). The effects of the RAS were classically described as mediated by angiotensin (Ang) II via angiotensin type 1 (AT1) receptors. However, another arm of the RAS formed by the angiotensin converting enzyme 2 (ACE2), Ang-(1-7) and the Mas receptor has been a matter of investigation due to its important physiological roles, usually counterbalancing the classical effects exerted by Ang II.
