Low Levels Of Brain-Derived Neurotrophic Factor (BDNF) And Long COVID Syndrome

Low serum BDNF levels correlate with severe SARS-CoV-2 infection. In addition, during a patient’s recovery, BDNF levels were restored. BDNF levels serve as a biomarker for the severity or progression of Long COVID, especially regarding neurological symptoms. 

Long COVID refers to the lingering symptoms experienced by some individuals after the acute phase of a COVID-19 infection. Here’s how BDNF is relevant to Long COVID:

  1. Neurological Symptoms in Long COVID: Many individuals with Long COVID experience neurological symptoms such as fatigue, brain fog, headaches, and even depression or anxiety. Since BDNF is crucial for brain health, including cognitive function and mood regulation, changes in BDNF levels or activity could contribute to these neurological symptoms.

  2. BDNF and Neuroinflammation: Long COVID may involve elements of neuroinflammation. BDNF has neuroprotective properties and plays a role in modulating neuroinflammatory responses. Therefore, altered BDNF signaling can influence the progression or severity of neuroinflammatory aspects of Long COVID.

  3. Role in Synaptic Plasticity and Repair: BDNF is important for synaptic plasticity and neurogenesis. In the context of Long COVID, where neural networks may be disrupted, BDNF could play a role in neural repair and the restoration of normal brain function.

  4. Stress Response: Long COVID can be a stressful experience, both physically and psychologically. BDNF is known to be affected by stress, which could in turn impact its levels and function in individuals with Long COVID.

  5. Interactions with Other Systems: BDNF interacts with various other physiological systems that could be impacted by Long COVID, including the immune system and the endocrine system. These interactions influence the overall health outcomes in Long COVID.

High levels Of Brain-Derived Neurotrophic Factor (BDNF): - Positive Effects On Brain Health And Function

High levels of Brain-Derived Neurotrophic Factor (BDNF) are generally associated with positive effects on brain health and function. Here are some of the key impacts and potential benefits of elevated BDNF levels:

  1. Enhanced Neuroplasticity: BDNF is crucial for neuroplasticity, the brain’s ability to form and reorganize synaptic connections, especially in response to learning and memory. Higher levels of BDNF can enhance this process, potentially improving learning and memory capabilities.

  2. Neuroprotection: Elevated BDNF levels offer neuroprotective benefits. They help in the survival and maintenance of neurons, and can protect against neurodegenerative processes and damage from neurotoxic substances.

  3. Improved Mood and Cognitive Function: High levels of BDNF are associated with better mood regulation and cognitive function. BDNF has been linked to a decreased risk of mood disorders like depression and anxiety.

  4. Support in Recovery from Neurological Injury: After brain injury or in neurodegenerative diseases, increased BDNF can aid in the recovery and regeneration of neural tissue.

  5. Enhanced Synaptic Transmission: BDNF facilitates synaptic transmission, thereby improving the efficiency of neural communication.

  6. Stress Resilience: BDNF can enhance the brain’s resilience to stress, improving the ability to cope with stressful situations and potentially reducing the impact of stress on mental health.

  7. Potential in Treating Neurological Disorders: Given its neuroprotective and neurogenerative properties, BDNF is being studied for its potential in treating conditions like Alzheimer’s disease, Parkinson’s disease, and stroke.

  8. Exercise and Diet Effects: Physical activity and certain diets (like those rich in omega-3 fatty acids) can increase BDNF levels, contributing to improved brain health and function.

 

While high BDNF levels are generally beneficial, it’s important to note that BDNF activity in the brain is finely tuned and context-dependent. Extremely high levels of BDNF in certain contexts or diseases could potentially have negative effects, although this is an area that requires more research. The balance and regulation of BDNF are critical for its beneficial effects.

Brain-Derived Neurotrophic Factor (BDNF), Microglia And Neuroinflammation

The relationship between Brain-Derived Neurotrophic Factor (BDNF) and microglia in the brain is an area of active research, highlighting the complex interactions within the nervous system. Microglia are a type of glial cell that act as the main form of active immune defense in the central nervous system. Here’s how BDNF and microglia interact and influence each other:

  1. Microglial Activation: BDNF can influence the activation state of microglia. Microglia exist in various states of activation, ranging from a resting state to an active state. The active state is usually in response to injury, infection, or disease, and in this state, microglia can release various cytokines and growth factors, including BDNF.

  2. Neuroprotection and Inflammation: BDNF released by microglia can have neuroprotective effects. It promotes the survival and health of neurons and can modulate the inflammatory response of microglia. This modulation is important in conditions like neurodegenerative diseases, where inflammation plays a key role.

  3. BDNF in Microglial Function: BDNF influences the functioning of microglia. It can affect their proliferation, migration, and phagocytic activity. These activities are crucial for the role of microglia in maintaining brain health, clearing debris, and responding to injury or disease.

  4. Impact on Synaptic Plasticity: Microglia are involved in synaptic pruning and remodeling, processes that are essential for synaptic plasticity. BDNF, released by neurons and microglia, plays a role in these processes, influencing learning and memory.

  5. Response to Brain Injury: Following brain injury, microglia are activated and can release BDNF as part of the response to injury. This release can aid in the repair and recovery processes of the brain.

  6. Involvement in Disease States: In various disease states, such as Alzheimer’s disease, Parkinson’s disease, and multiple sclerosis, the interaction between BDNF and microglia can be altered. Understanding these alterations is important for developing therapeutic strategies.

  7. Bidirectional Communication: There is a bidirectional communication between neurons and microglia, where BDNF plays a role. Neurons can influence microglial activity, and microglia can affect neuronal health, partly mediated by BDNF.

 

In summary, the interaction between BDNF and microglia is multifaceted, influencing neuroinflammation, neuroprotection, synaptic plasticity, and responses to brain injury. This interaction is a significant area of interest in understanding and treating various neurological and psychiatric disorders.

Kynurenine Pathway of Tryptophan Metabolism and Neuroinflammation

The kynurenine pathway (KP) of tryptophan metabolism plays a crucial role in the balance between neuroprotection and neurotoxicity. Dysregulation of this pathway has been associated with several neurodegenerative and neuropsychiatric disorders, largely due to the potential role of KP metabolites in mediating neuroinflammation.

  1. Initiation of the Pathway: The metabolism of tryptophan via the kynurenine pathway begins with its conversion into kynurenine. This step is catalyzed by two primary enzymes: indoleamine 2,3-dioxygenase (IDO) and tryptophan 2,3-dioxygenase (TDO). Both enzymes can be induced by pro-inflammatory stimuli, especially IDO, which is upregulated by pro-inflammatory cytokines like interferon-gamma (IFN-γ).
  2. Neuroactive Metabolites:
    1. Kynurenic Acid (KYNA): Produced in astrocytes, KYNA acts as an antagonist at NMDA and α7 nicotinic acetylcholine receptors. It has neuroprotective effects but, in elevated concentrations, might also contribute to cognitive dysfunctions.
    2. Quinolinic Acid (QUIN): This is synthesized in microglia and acts as an NMDA receptor agonist. Elevated levels can lead to excitotoxicity, which is damaging to neurons and is associated with several neurodegenerative conditions.
  3. Neuroinflammation: An imbalance favoring the production of QUIN over KYNA can contribute to neuroinflammation. QUIN’s agonistic action on NMDA receptors can lead to excitotoxic neuronal death. Moreover, QUIN can generate reactive oxygen species (ROS) and exacerbate inflammation. Chronic inflammation can upregulate IDO, leading to a sustained increase in kynurenine metabolites, which further skews the balance towards neurotoxic effects.
  4. Role in Neurodegenerative Diseases: Dysregulation of the kynurenine pathway is observed in various neurodegenerative conditions, including:
    1. Alzheimer’s Disease (AD): Elevated levels of QUIN and reduced KYNA levels have been reported in the brains of AD patients. QUIN can promote amyloid-beta aggregation, a hallmark of AD pathology.
    2. Parkinson’s Disease (PD): KP dysregulation is suggested to be involved in the dopaminergic neuronal loss characteristic of PD.
    3. Huntington’s Disease (HD): Elevated QUIN levels have been observed in the brains of HD patients and are believed to contribute to the striatal neurodegeneration seen in HD.
  5. Neuropsychiatric Implications: Changes in the KP have also been associated with neuropsychiatric disorders like depression, schizophrenia, and bipolar disorder. The balance between KYNA and QUIN can influence neurotransmission, synaptic plasticity, and neural integrity, potentially leading to mood and cognitive disturbances.

Test Details

Microglia are a type of glial cell that act as the main form of active immune defense in the central nervous system.

Brain-Derived Neurotrophic Factor (BDNF) plays a significant role in the context of neuroinflammation, an inflammatory response within the brain or spinal cord. Neuroinflammation is a characteristic feature of various neurological disorders, including multiple sclerosis, Alzheimer’s disease, Parkinson’s disease, and even in response to traumatic brain injury. Clinical studies show that levels of BDNF are decreased in the presence of neuroinflammation and also in cases of long COVID. Increasing BDNF levels have been shown to have anti-inflammatory effects throughout the human body.

Here’s how BDNF interacts with neuroinflammation:

  1. Neuroprotective Effects: BDNF has neuroprotective properties. It supports the survival and function of neurons and can promote healing and recovery in the nervous system. In conditions of neuroinflammation, BDNF can help mitigate neuronal damage.

  2. Modulation of Inflammatory Responses: BDNF can influence the immune cells in the brain, including microglia (the primary immune cells in the CNS) and astrocytes. By affecting these cells, BDNF can potentially modulate inflammatory responses within the brain.

  3. Impact on Microglial Activation: Microglia, when activated in response to injury or disease, can release pro-inflammatory cytokines that exacerbate neuroinflammation. BDNF can modulate microglial activation, potentially reducing the release of these pro-inflammatory factors.

  4. BDNF in Neurodegenerative Diseases: In neurodegenerative diseases characterized by chronic neuroinflammation, BDNF levels are often found to be altered. Enhancing BDNF signaling in these conditions might be a potential therapeutic strategy to counteract neuroinflammation and its deleterious effects on neurons.

  5. Involvement in Recovery and Repair: BDNF not only helps protect neurons from inflammatory damage but also supports neurogenesis (the growth of new neurons) and synaptic plasticity, which are crucial for recovery and repair in the nervous system.

  6. Balance and Regulation: The relationship between BDNF and neuroinflammation is complex and involves a balance. While BDNF generally has protective and anti-inflammatory effects, its role can vary depending on the context and stage of disease or injury.

  7. Therapeutic Potential: Understanding how BDNF interacts with pathways involved in neuroinflammation opens up potential therapeutic avenues, especially for conditions where neuroinflammation is a key pathological feature.

In summary, BDNF is an important modulator of neuroinflammatory processes, with the potential to both protect against and mitigate the effects of inflammation in the nervous system. Its role in neurodegenerative diseases and conditions involving neuroinflammation makes it a significant target for research and potential therapeutic intervention.
