There is a critical need to understand the structural and cellular components that play a vital role in the pathophysiology of retinal diseases. One potential component is the family of structural proteins called small leucine-rich proteoglycans (SLRPs). SLRPs are crucial in many fundamental biological processes involved in the maintenance of retinal homeostasis. They are present within the extracellular matrix (ECM) of connective and vascular tissues and contribute to tissue organization and modulation of cell growth. They play a vital role in cell\u2013matrix interactions in many upstream signaling pathways involved in fibrillogenesis and angiogenesis. In this comprehensive review, we describe the expression patterns and function of SLRPs in the retina, including Biglycan and Decorin from class I; Fibromodulin, Lumican, and a Proline\/arginine-rich end leucine-rich repeat protein (PRELP) from class II; Opticin and Osteoglycin\/Mimecan from class III; and Chondroadherin (CHAD), Tsukushi and Nyctalopin from class IV.<\/jats:p>","DOI":"10.3390\/ijms22147293","type":"journal-article","created":{"date-parts":[[2021,7,7]],"date-time":"2021-07-07T12:31:25Z","timestamp":1625661085000},"page":"7293","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":25,"title":["Small Leucine-Rich Proteoglycans (SLRPs) in the Retina"],"prefix":"10.3390","volume":"22","author":[{"given":"Shermaine W.
