Immigrant Youths with Disabilities and Caregivers from the Middle-East—Challenges and Needs During Transition to Adulthood

Background: Recent years of research have increased the knowledge about how to support the transition to adulthood for youths with disabilities. In today’s multi-cultural societies knowledge about transitioning immigrant youths and their caregivers is still needed.Objective: To describe the expectations and needs of immigrant youths with disabilities residing in Sweden during their transition into adulthood as well as the expectations and needs of their caregivers, all of whom come from Arabic-speaking countries.Method: Structured interviews based on the Rotterdam Transition Profile (RTP) questionnaire were conducted with youths 16 to 24 years of age and with caregivers based on the Family Needs Survey (FNS).Results: Findings of interest were the youths´ dependence on parents for care demands and leisure activities, their need for information regarding future care and support and their concerns regarding future marriage. Caregivers’ felt unfamiliar with the term ‘intellectual disability’ and had a need for information about their youths’ condition and of available service for their children now and in the future.Conclusion: To prepare immigrant youths for future support, health care and habilitation services, it is important to enhance their autonomy. Immigrant families need culturally sensitive support and information, provided by designated professionals in their language of preference during the youths’ transition to adulthood

Inhibition of plasminogen activator inhibitor-1 binding to endocytosis receptors of the low-density-lipoprotein receptor family by a peptide isolated from a phage display library

The functions of the serpin PAI-1 (plasminogen activator inhibitor-1) are based on molecular interactions with its target proteases uPA and tPA (urokinase-type and tissue-type plasminogen activator respectively), with vitronectin and with endocytosis receptors of the low-density-lipoprotein family. Understanding the significance of these interactions would be facilitated by the ability to block them individually. Using phage display, we have identified the disulfide-constrained peptide motif CFGWC with affinity for natural human PAI-1. The three-dimensional structure of a peptide containing this motif (DVPCFGWCQDA) was determined by liquid-state NMR spectroscopy. A binding site in the so-called flexible joint region of PAI-1 was suggested by molecular modelling and validated through binding studies with various competitors and site-directed mutagenesis of PAI-1. The peptide with an N-terminal biotin inhibited the binding of the uPA–PAI-1 complex to the endocytosis receptors low-density-lipoprotein-receptor-related protein 1A (LRP-1A) and very-low-density-lipoprotein receptor (VLDLR) in vitro and inhibited endocytosis of the uPA–PAI-1 complex in U937 cells. We conclude that the isolated peptide represents a novel approach to pharmacological interference with the functions of PAI-1 based on inhibition of one specific molecular interaction
