Study proteins implicated in neurodegenerative disorders

Thermo Fisher Scientific offers a wide selection of sensitive and accurate immunoassays for neurobiology and neuroscience research. These assays include ELISA kits and multiplex immunoassays (for the Luminex technology platform) that allow quantification of biomarkers in cerebrospinal fluid (CSF), plasma, and serum for neuroinflammation, neurodegeneration, traumatic brain injury, and variety of conditions and diseases of the central nervous system (CNS).

Overview of neurobiology

Quantification of protein biomarkers is critical for neurobiology and neuroscience research and antibody-based techniques, such as enzyme-linked immunosorbent assays (ELISA) and multiplex immunoassays, offer powerful tools to achieve sensitive quantification. These proteins include neurodegenerative disease biomarkers, traumatic brain injury biomarkers, including those released due to astroglial, axonal, and neuronal cell body injury, neurotrophic factors (NTFs) that play a key role in the development of neurons, their plasticity, protection, repair, and key cytokines and chemokines that are involved in central nervous system (CNS) tissue homeostasis and neuroinflammation (Figure 1).

A variety of conditions or diseases of the CNS including brain trauma, stroke, multiple sclerosis, Parkinson’s disease, or Alzheimer’s disease can trigger neuroinflammation and dysfunction of blood-brain barrier (BBB). Acting in concert with aging, epigenetics, the environment, and other risk factors can strongly influence the onset and progression of these diseases. For example, traumatic brain injury has been established as a risk factor for the development of neurodegenerative diseases and dementia at later stages of life. In response to insults that perturb homeostasis in the CNS, a rapid and early activation of the glial cells form the acute inflammatory response. This leads to the repair of the damaged area but if the challenge is not cleared and persists, the activation of the response is exaggerated, becomes chronic, and can result in tissue degeneration and even the drastic loss of BBB integrity.

Key targets for neurodegeneration:

  • Amyloid-beta (Aβ, beta amyloid, or Abeta), which is crucially involved in Alzheimer's disease as the main component of the amyloid plaques found in the brains of Alzheimer’s patients.
  • Tau, a protein which stabilizes microtubules and which, when not functioning properly, is implicated in pathologies and dementias of the nervous system.
  • Alpha synuclein (α-synuclein), which is thought to play an important role in maintaining a supply of synaptic vesicles in presynaptic terminals and may also help regulate the release of dopamine.

Key targets for traumatic brain injury:

  • Glial fibrillary acidic protein (GFAP) is a monomeric intermediate filament (IF) protein found in the astroglial cytoskeleton. This protein is not found outside the central nervous system and is only released after cell death or injury, when it may be detected in the blood.
  • S100B is a calcium-sensor protein that is highly expressed in astrocytes but also present in other cells of the nervous system, including oligodendrocytes, Schwann cells, and ependymal cells. Elevated S100B levels in biological fluids has been shown to be a biomarker for acute brain injury.
  • Neurofilament—Heavy (NF-H) and Light (NF-L) are subunits of the neurofilament scaffolding protein of neurons. Neuronal damage can cause the release of neurofilament into the interstitial fluid and subsequently to the cerebrospinal fluid and the blood.
  • Ubiquitin C-terminal hydrolase (UCH-L1) is a brain-specific deubiquitinating enzyme. Elevated cerebrospinal fluid and blood concentrations of UCH-L1 have been associated with traumatic brain injury.

Key targets for neuroinflammation:

  • Brain-derived neurotrophic factor (BDNF) is a neurotrophin that induces the maintenance, survival, plasticity, and neurotransmitter regulation of neurons, and neurodegenerative disorders often have reduced BDNF concentrations in blood and brain.
  • Nerve growth factor (NGF) is a neurotrophin that induces the survival, development, and function of neurons and has been shown to have direct and indirect effects on immune response.
  • Proinflammatory cytokines, which include tumor necrosis factor (TNF)-α, interleukin (IL)-1, IL-6, IL-8

Neurobiology QuantiGene multiplex assays

QuantiGene Plex assays offer an accurate and precise method for the detection and quantification of multiple DNA and RNA targets. This assay utilizes branched DNA signal amplification technology to enable the measurement of gene expression levels in a variety of sample types, including blood, tissue, FFPE samples, and cell lysates with no RNA purification required. The ability to simultaneously measure up to 80 targets in a single sample allows researchers to gain a comprehensive view of neurobiological events, helping provide critical insights into the dynamic processes underlying brain development, function, and neurological disorders and diseases.

There are several advantages to bead-based assays over traditional methods of gene expression analysis. QuantiGene Plex supports a highly multiplexed approach, allowing for the simultaneous measurement of multiple targets in a single sample using the same Luminex xMAP technology as ProcartaPlex. This capability not only helps save time and resources but also provides a thorough understanding of gene expression patterns. The assay is robust and highly sensitive, enabling the detection of low-abundance targets with high precision. Without the need for traditional RNA extraction and purification, the lyse-and-go method of QuantiGene Plex helps reduce potential variability and helps save valuable time.

QuantiGene Plex gene expression assays are available in two formats to suit your individual research needs related to neurobiology research. You can choose from a selection of carefully curated preconfigured panels, each targeting a specific set of genes or pathways of interest (Table 5) or use the Panel Configurator to create your own customized panel in 5 easy steps. A few examples of published data using custom QuantiGene plex assays are highlighted in Table 4.

Overview of neurobiology

Quantification of protein biomarkers is critical for neurobiology and neuroscience research and antibody-based techniques, such as enzyme-linked immunosorbent assays (ELISA) and multiplex immunoassays, offer powerful tools to achieve sensitive quantification. These proteins include neurodegenerative disease biomarkers, traumatic brain injury biomarkers, including those released due to astroglial, axonal, and neuronal cell body injury, neurotrophic factors (NTFs) that play a key role in the development of neurons, their plasticity, protection, repair, and key cytokines and chemokines that are involved in central nervous system (CNS) tissue homeostasis and neuroinflammation (Figure 1).

A variety of conditions or diseases of the CNS including brain trauma, stroke, multiple sclerosis, Parkinson’s disease, or Alzheimer’s disease can trigger neuroinflammation and dysfunction of blood-brain barrier (BBB). Acting in concert with aging, epigenetics, the environment, and other risk factors can strongly influence the onset and progression of these diseases. For example, traumatic brain injury has been established as a risk factor for the development of neurodegenerative diseases and dementia at later stages of life. In response to insults that perturb homeostasis in the CNS, a rapid and early activation of the glial cells form the acute inflammatory response. This leads to the repair of the damaged area but if the challenge is not cleared and persists, the activation of the response is exaggerated, becomes chronic, and can result in tissue degeneration and even the drastic loss of BBB integrity.

Key targets for neurodegeneration:

  • Amyloid-beta (Aβ, beta amyloid, or Abeta), which is crucially involved in Alzheimer's disease as the main component of the amyloid plaques found in the brains of Alzheimer’s patients.
  • Tau, a protein which stabilizes microtubules and which, when not functioning properly, is implicated in pathologies and dementias of the nervous system.
  • Alpha synuclein (α-synuclein), which is thought to play an important role in maintaining a supply of synaptic vesicles in presynaptic terminals and may also help regulate the release of dopamine.

Key targets for traumatic brain injury:

  • Glial fibrillary acidic protein (GFAP) is a monomeric intermediate filament (IF) protein found in the astroglial cytoskeleton. This protein is not found outside the central nervous system and is only released after cell death or injury, when it may be detected in the blood.
  • S100B is a calcium-sensor protein that is highly expressed in astrocytes but also present in other cells of the nervous system, including oligodendrocytes, Schwann cells, and ependymal cells. Elevated S100B levels in biological fluids has been shown to be a biomarker for acute brain injury.
  • Neurofilament—Heavy (NF-H) and Light (NF-L) are subunits of the neurofilament scaffolding protein of neurons. Neuronal damage can cause the release of neurofilament into the interstitial fluid and subsequently to the cerebrospinal fluid and the blood.
  • Ubiquitin C-terminal hydrolase (UCH-L1) is a brain-specific deubiquitinating enzyme. Elevated cerebrospinal fluid and blood concentrations of UCH-L1 have been associated with traumatic brain injury.

Key targets for neuroinflammation:

  • Brain-derived neurotrophic factor (BDNF) is a neurotrophin that induces the maintenance, survival, plasticity, and neurotransmitter regulation of neurons, and neurodegenerative disorders often have reduced BDNF concentrations in blood and brain.
  • Nerve growth factor (NGF) is a neurotrophin that induces the survival, development, and function of neurons and has been shown to have direct and indirect effects on immune response.
  • Proinflammatory cytokines, which include tumor necrosis factor (TNF)-α, interleukin (IL)-1, IL-6, IL-8

Neurobiology QuantiGene multiplex assays

QuantiGene Plex assays offer an accurate and precise method for the detection and quantification of multiple DNA and RNA targets. This assay utilizes branched DNA signal amplification technology to enable the measurement of gene expression levels in a variety of sample types, including blood, tissue, FFPE samples, and cell lysates with no RNA purification required. The ability to simultaneously measure up to 80 targets in a single sample allows researchers to gain a comprehensive view of neurobiological events, helping provide critical insights into the dynamic processes underlying brain development, function, and neurological disorders and diseases.

There are several advantages to bead-based assays over traditional methods of gene expression analysis. QuantiGene Plex supports a highly multiplexed approach, allowing for the simultaneous measurement of multiple targets in a single sample using the same Luminex xMAP technology as ProcartaPlex. This capability not only helps save time and resources but also provides a thorough understanding of gene expression patterns. The assay is robust and highly sensitive, enabling the detection of low-abundance targets with high precision. Without the need for traditional RNA extraction and purification, the lyse-and-go method of QuantiGene Plex helps reduce potential variability and helps save valuable time.

QuantiGene Plex gene expression assays are available in two formats to suit your individual research needs related to neurobiology research. You can choose from a selection of carefully curated preconfigured panels, each targeting a specific set of genes or pathways of interest (Table 5) or use the Panel Configurator to create your own customized panel in 5 easy steps. A few examples of published data using custom QuantiGene plex assays are highlighted in Table 4.
