ABSTRACT

INTRODUCTION: The 37/67 kDa high-affinity laminin receptor (laminin receptor precursor/laminin receptor, LRP/LR) is a multi-faceted cellular receptor. It plays a vital role in the malignancy of various cancer types where it is seen to contribute to invasion, adhesion, apoptosis evasion and angiogenesis. Furthermore, it has been found to play an important role in facilitating the processes leading to neurotoxicity in Alzheimer's disease (AD). Various therapeutic options targeting this receptor have been patented with the outlook on application for the treatment/prevention of these diseases. AREAS COVERED: The various roles that LRP/LR plays in cancer, AD and infectious diseases caused by viruses and bacteria have been examined in detail and an overview of the current patented therapeutic strategies targeting this receptor is given. EXPERT OPINION: Molecular tools directed against LRP/LR, such as antibodies and small interfering RNA, could prove to be effective in the prevention of metastasis and angiogenesis while inducing apoptosis in cancers. Moreover, these strategies could also be applied to AD where LRP/LR is seen to facilitate the production and internalization of the neurotoxic Aß peptide. This review provides a comprehensive overview of the mechanisms by which LRP/LR is involved in eliciting pathogenic events, while showing how the use of patented approaches targeting this receptor could be used to treat them.

ABSTRACT

IMPORTANCE OF THE FIELD: The 37/67 kDa laminin receptor precursor/laminin receptor (LRP/LR) represents a multifunctional protein located on the cell surface, in the cytosol and the nucleus. The receptor acts as a mediator for cell adhesion, cell proliferation and cell differentiation. It is a key player in invasion and adhesion, major functions of several important metastatic cancer types. The receptor hampers apoptosis thereby favoring cancer progression. LRP/LR plays a major role as a cell surface receptor in prion disorders and may be of considerable importance for other neurodegenerative diseases such as Alzheimer's disease. A series of viruses including Sindbis virus, Dengue virus and Adeno-associated virus use LRP/LR as attachment receptors. Bacteria and Candida albicans use the receptor for pathogenesis. AREAS COVERED IN THIS REVIEW: Background and patented biological approaches for therapeutic modulation of LRP/LR in neurodegenerative diseases, cancer, viral disorders, bacterial and yeast infections. WHAT THE READER WILL GAIN: A comprehensive review of the role of LRP/LR in infectious and non-infectious diseases and an insightful assessment of published or patented biological approaches for the therapeutic modulation of LRP/LR. TAKE HOME MESSAGE: Molecular tools such as antibodies directed against LRP/LR have the potential to act as promising alternative therapeutics for the treatment of various diseases.
