Retinol-binding protein (RBP) and pigmentary dystrophy of the retina.
Vitamin A (retinol) is a fat-soluble alcohol and is derived in the upper part of the small intestine from carotenoid plant pigments and Vitamin A esters present in food (Olson, I964). The free retinol then penetrates through the mucosal cells, perhaps aided by its polar or hydrophilic hydroxy group, and is re-esterified during transit (Glover and Walker, I 964). After absorption it reaches the ...
متن کاملPrealbumin-retinol-binding-protein-retinol complex in hemodialysis patients.
In hemodialysis (HD) patients, serum prealbumin (TBPA) is correlated to nutritional status and outcome despite usually elevated serum levels. The purpose of this work was to study the role of TBPA-retinol-binding-protein (RBP)-retinol complex changes in the elevation of serum TBPA in HD patients. Serum TBPA, RBP, and retinol were measured in 30 otherwise healthy HD patients (15 men, 15 women) a...
متن کاملRetinol and retinol-binding protein: gut integrity and circulating immunoglobulins.
Vitamin A (retinol) is required to maintain immunity and epithelial turnover and is a key micronutrient needed for combating infection. Vitamin A actions on the immune system are diverse and cannot be accounted for by a single effect or mechanism. The actions of retinol in maintaining gut integrity in humans and immunoglobulin levels in mice was investigated. For 30 children, performance on the...
متن کاملMuscle expression of human retinol-binding protein (RBP). Suppression of the visual defect of RBP knockout mice.
Mice lacking retinol-binding protein (RBP) have low circulating retinol levels. They have severe visual defects due to a low content of retinol or retinyl esters in the eye. A transgenic mouse strain that expresses human RBP under the control of the muscle creatine kinase promoter in the null background was generated. The exogenous protein bound retinol and transthyretin in the circulation and ...
متن کاملLoss of retinol-binding properties for plasma retinol-binding protein in normal human epidermis.
Terminal differentiation of the keratinocytes (cornification) has been linked to a restricted supply of retinol. Retinol is distributed to target cells by the retinol-binding protein (RBP), which circulates in the plasma in complex with transthyretin (TTR). In this study we have addressed the question of retinol delivery to the epidermis via RBP. Retinol radiobinding assays, affinity chromatogr...
