| Gene Target | Biological Function | Application as a Biomarker |
|---|---|---|
| 5-hydroxytryptamine receptor 2A (HTR2A) | 5-hydroxytryptamine receptor 2A (HTR2A) is a G protein-coupled receptor that binds the neurotransmitter serotonin (5-hydroxytryptamine, 5-HT). It is predominantly expressed in the central nervous system, especially in cortical and limbic regions, as well as in peripheral tissues. Upon serotonin binding, HTR2A activates phospholipase C via Gq/11 proteins, leading to increased intracellular inositol triphosphate (IP3) and diacylglycerol (DAG), which subsequently mobilize intracellular calcium and activate protein kinase C. HTR2A modulates a variety of physiological processes, including mood, cognition, perception, and vascular smooth muscle contraction. It is also a principal target for several psychoactive compounds, including certain antipsychotics and hallucinogens. | HTR2A has been investigated as a biomarker in neuropsychiatric and neurodevelopmental disorders, such as schizophrenia, depression, and autism spectrum disorder. Studies have examined HTR2A gene polymorphisms, mRNA expression levels, and receptor binding densities in relation to disease risk, symptom profiles, and response to pharmacological treatments. Additionally, altered HTR2A expression or function has been reported in post-mortem brain tissue and peripheral blood samples from affected individuals. These findings have supported its use in research settings for studying disease mechanisms, stratifying patient populations, and investigating pharmacogenetic associations. |
| amyloid beta precursor protein (APP) | Amyloid beta precursor protein (APP) is a transmembrane glycoprotein widely expressed in many tissues, including the central nervous system. APP undergoes proteolytic processing via two main pathways: the non-amyloidogenic pathway, which precludes amyloid beta (Aβ) formation, and the amyloidogenic pathway, which results in the generation of Aβ peptides. These peptides can aggregate to form amyloid plaques, a hallmark of Alzheimer's disease. Beyond its role in Aβ production, APP is involved in neuronal development, synaptic formation and repair, cell signaling, and cell adhesion. | APP and its cleavage products, particularly amyloid beta (Aβ) peptides, are measured in cerebrospinal fluid (CSF) and plasma as indicators of amyloid pathology. Altered levels of Aβ peptides, such as Aβ42 and the Aβ42/Aβ40 ratio, are used in research and clinical settings to assess amyloid deposition in the brain, most notably in Alzheimer's disease. These measurements assist in the evaluation of disease presence, progression, and response to therapy. |
| dopamine receptor D2 (DRD2) | Dopamine receptor D2 (DRD2) is a G protein-coupled receptor that mediates the physiological actions of dopamine, an important neurotransmitter in the central nervous system. DRD2 is primarily expressed in the striatum and other brain regions involved in motor control, cognition, motivation, and reward. Upon dopamine binding, DRD2 inhibits adenylyl cyclase activity, decreasing intracellular cAMP levels, and modulates neuronal excitability and synaptic transmission. DRD2 exists in two isoforms, D2 short and D2 long, which have distinct but overlapping functions in pre- and postsynaptic signaling. The receptor plays a central role in regulating dopaminergic neurotransmission and is implicated in the modulation of movement, emotional responses, and several neuropsychiatric processes. | DRD2 has been studied as a biomarker in various neuropsychiatric and neurological conditions, including schizophrenia, Parkinson's disease, and substance use disorders. Alterations in DRD2 expression, binding availability, or genetic variants have been associated with disease risk, symptom severity, and response to pharmacological treatments, particularly antipsychotic medications that target DRD2. Imaging of DRD2 using positron emission tomography (PET) or single-photon emission computed tomography (SPECT) has been utilized in research to assess receptor density and occupancy in vivo. DRD2 genotyping and measurement of receptor levels have been explored for their potential to inform diagnosis, prognosis, and therapeutic strategies. |
