Collagen type VI, which forms characteristic microfibrillar structures, is assembled from three individual alpha(VI) chains that form a short triple helix and two adjacent globular domains. Expression of all three alpha (VI) collagen chains in the human bone marrow (BM) microenvironment could be detected by chain-specific antibodies in tissue sections and in the adherent stromal layer of long-term BM cultures. In functional studies, collagen type VI was shown to be a strong adhesive substrate for various hematopoietic cell lines and light-density BM mononuclear cells. The adhesive site within the molecule seems to be restricted to the triple helical domain of all three alpha (VI) chains, because individual alpha (VI) chains were not active in the attachment assays. Adhesion of the hematopoietic cell lines to collagen VI was dose-dependent and could be inhibited by heparin. Although the triple helix contains several RGD sequences, adhesion of the hematopoietic cell types to collagen VI could be blocked neither by RGD-containing peptides nor by a neutralizing antibody to the beta 1 integrin subunit. In combination with an antiadhesive substrate, the binding properties of collagen VI could be downregulated. These data suggest that this collagen type may play an important role in the adhesion of hematopoietic cells within the BM microenvironment.

Abstract Background To date, the genetic contribution to Parkinson’s disease (PD) remains unclear. Mutations in the collagen type VI alpha 3 (COL6A3) gene were recently identified as a cause of isolated dystonia. Since PD and dystonia are closely related disorders with shared clinical and genetic characteristics, we explored the association between COL6A3 and PD in a Chinese cohort. Methods We performed genetic screening of COL6A3 in a Chinese cohort of 173 patients with sporadic PD and 200 healthy controls. We identified variants that are likely to have pathogenic effects based on: 1) a minor allele frequency of < 0.01; and 2) the variant being recognized as deleterious by at least 15 different in silico predicting tools. Finally, we tested the aggregate burden of COL6A3 on PD via SKAT-O analysis. Results First, we found compound heterozygous COL6A3 gene mutations in one early-onset PD patients. Then, we explored whether COL6A3 variants contributed to increased risk of developing PD in a Chinese population. We detected 21 rare non-synonymous variants. Pathogenicity predictions identified seven novel non-synonymous variants as likely to be pathogenic. SKAT-O analysis further revealed that an aggregate burden of variants in COL6A3 contributes to PD (p = 0.03). Conclusion An increased aggregate burden of the COL6A3 gene was detected in patients with PD.
