Receptor on neural membrane that induces development of Glioma-
**Core Concept**
Receptor on neural membrane that induces development of Glioma refers to the oncogenic receptor tyrosine kinases (RTKs) involved in glioma pathogenesis. Gliomas are a type of brain tumor that originates from glial cells, and certain RTKs can contribute to their development and progression.
**Why the Correct Answer is Right**
The correct receptor is the epidermal growth factor receptor (EGFR), particularly the EGFRvIII mutation, which is a common oncogenic mutation in glioblastoma, a type of glioma. This mutation leads to the constitutive activation of EGFR, promoting cell proliferation, survival, and angiogenesis. The EGFR signaling pathway involves the binding of EGF to EGFR, which activates downstream effectors such as PI3K/AKT and MAPK/ERK pathways, contributing to glioma development and progression.
**Why Each Wrong Option is Incorrect**
**Option A:** PDGFR (Platelet-Derived Growth Factor Receptor) is involved in glioma development but is not the primary receptor associated with glioma pathogenesis.
**Option B:** VEGFR (Vascular Endothelial Growth Factor Receptor) is crucial for angiogenesis in gliomas but is not directly involved in the development of gliomas.
**Option C:** NMDA receptors are involved in neuronal excitability and synaptic plasticity but are not directly associated with glioma development.
**Clinical Pearl / High-Yield Fact**
The EGFRvIII mutation is a characteristic marker of glioblastoma, and its presence can be used as a diagnostic and prognostic marker. Targeting EGFR with tyrosine kinase inhibitors or monoclonal antibodies is a therapeutic strategy for glioblastoma treatment.
**Correct Answer:** D.
