AAV receptor (AAVR)

Target
AAVR
Molecular classification
Receptor, Cell-surface protein
01

Overview

The AAV receptor (AAVR) is a cell-surface protein that serves as the primary point of entry for adeno-associated virus vectors in mammalian cells[2][5]. Engineering the interaction between AAV capsids and cell-surface receptors (AAVR or tissue-specific proteins such as integrins) enables selective and efficient gene delivery to neuromuscular tissue[4][3]. Strategies include overexpression of AAVR, capsid engineering to enhance receptor affinity, and development of AAV variants with tissue selectivity, which collectively improve transduction efficiency and the safety profile of gene therapy for diseases such as muscular dystrophies[3][4].

02

Mechanism of action

Enhanced tissue-specific gene transduction by engineered AAV capsids binding selectively to AAVR or muscle/tissue-enriched receptors

03

Biological functions

Mediates adeno-associated virus entry into cellsRegulates gene delivery efficiency and tissue specificity
04

Disease associations

Gene therapy for neuromuscular diseases, e.g., muscular dystrophiesOther roles depend on the engineered vector and tissue targeting strategy
05

Safety considerations

Immune response to viral capsid or transgene productOff-target transduction leading to ectopic gene expressionInflammatory responses in injected tissues, especially with certain AAV serotypes
06

Biomarkers

Expression level of AAVR in target tissue for gene therapy efficiency prediction
