TL;DR: Cationic polymers could overcome the surfactant barrier which inhibited airway cell transfection mediated by cationic lipids and give similar levels of lung luciferase expression by targeting differentAirway cell populations.
Abstract: Biodistribution of nonviral cationic vector/DNA complexes was studied after systemic or intratracheal administration to the lungs and correlated with transgene expression. Intravenous injection in C57Bl/6 mice gave maximal and significant luciferase expression in the lungs with the cationic polymer PEI 22K/DNA complexes at the highest ratios of positive/negative charges versus DNA alone. While DOTAP/DNA complexes with high charge ratio determined lower but still significant luciferase activity versus uncomplexed DNA, GL-67A and PEI 25K mediated negligible luciferase expression. Labelled PEI 22K and DOTAP complexes were evenly distributed in the alveolar region, where GFP expression was revealed, while PEI 25K and GL-67A complexes were not detected, suggesting a different interaction of these complexes with the plasma membrane of endothelial cells. Following an intratracheal injection, the highest and significant levels of transfection were obtained with slightly positive PEI complexes as compared with DNA alone, whereas cationic lipid-based vectors, DOTAP and GL-67A, gave not significant luciferase activity. Both types of polyplexes gave similar levels of lung luciferase expression by targeting different airway cell populations. PEI 25K complexes determined high levels of GFP in the bronchial cells, confirming confocal data on fluorescent complexes internalization. PEI 22K complexes gave mainly high GFP signal in the distal tract of the bronchial tree, where tagged complexes were recovered. Fluorescent lipid complexes were found in aggregates in the lumen of bronchi totally (DOTAP) or partially (GL-67A) co-localizing with surfactant protein A. Results indicated that cationic polymers could overcome the surfactant barrier which inhibited airway cell transfection mediated by cationic lipids.

TL;DR: In this paper, the authors studied the risk factors for adverse outcomes in patients with hematological malignancies (HM) who developed COVID-19 and analyzed predictors of mortality.
Abstract: Patients with hematological malignancies (HM) are at high risk of mortality from SARS-CoV-2 disease 2019 (COVID-19). A better understanding of risk factors for adverse outcomes may improve clinical management in these patients. We therefore studied baseline characteristics of HM patients developing COVID-19 and analyzed predictors of mortality. The survey was supported by the Scientific Working Group Infection in Hematology of the European Hematology Association (EHA). Eligible for the analysis were adult patients with HM and laboratory-confirmed COVID-19 observed between March and December 2020. The study sample includes 3801 cases, represented by lymphoproliferative (mainly non-Hodgkin lymphoma n = 1084, myeloma n = 684 and chronic lymphoid leukemia n = 474) and myeloproliferative malignancies (mainly acute myeloid leukemia n = 497 and myelodysplastic syndromes n = 279). Severe/critical COVID-19 was observed in 63.8% of patients (n = 2425). Overall, 2778 (73.1%) of the patients were hospitalized, 689 (18.1%) of whom were admitted to intensive care units (ICUs). Overall, 1185 patients (31.2%) died. The primary cause of death was COVID-19 in 688 patients (58.1%), HM in 173 patients (14.6%), and a combination of both COVID-19 and progressing HM in 155 patients (13.1%). Highest mortality was observed in acute myeloid leukemia (199/497, 40%) and myelodysplastic syndromes (118/279, 42.3%). The mortality rate significantly decreased between the first COVID-19 wave (March–May 2020) and the second wave (October–December 2020) (581/1427, 40.7% vs. 439/1773, 24.8%, p value < 0.0001). In the multivariable analysis, age, active malignancy, chronic cardiac disease, liver disease, renal impairment, smoking history, and ICU stay correlated with mortality. Acute myeloid leukemia was a higher mortality risk than lymphoproliferative diseases. This survey confirms that COVID-19 patients with HM are at high risk of lethal complications. However, improved COVID-19 prevention has reduced mortality despite an increase in the number of reported cases.

TL;DR: In this paper, the authors investigated whether the receptors located inside and outside cave-olar microdomains initiate different signalling pathways and how this may lead to opposite effects on cell proliferation.
Abstract: We have recently shown that oxytocin inhibits cell proliferation when the vast majority of oxytocin receptors are excluded from caveolin-1-enriched microdomains, and that, on the contrary, it has a mitogenic effect when the receptors are targeted to these plasma membrane domains. In this study, we investigated whether the receptors located inside and outside caveolar microdomains initiate different signalling pathways and how this may lead to opposite effects on cell proliferation. Our data indicate that, depending on their localization, oxytocin receptors transactivate EGFR and activate ERK1/2 using different signalling intermediates. The final outcome is a different temporal pattern of EGFR and ERK1/2 phosphorylation, which is more persistent when the receptors are located outside caveolar microdomains and inhibit cell growth, and very transient when they are located in caveolar microdomains and stimulate cell growth. Finally, only the activation of receptors located outside caveolar microdomains correlates with the activation of the cell cycle inhibitor p21(WAF1/CIP1), thus suggesting that the antiproliferative OTR effects may, in this case, be achieved by a sustained activation of EGFR and MAPK leading to the induction of this cell cycle regulator.

TL;DR: The longer spacer of glycines, the more effective is the functional motif in both eliciting NSCs adhesion, improving their viability and increasing their differentiation.
Abstract: The understanding of phenomena involved in the self-assembling of bio-inspired biomaterials acting as three-dimensional scaffolds for regenerative medicine applications is a necessary step to develop effective therapies in neural tissue engineering. We investigated the self-assembled nanostructures of functionalized peptides featuring four, two or no glycine-spacers between the self-assembly sequence RADA16-I and the functional biological motif PFSSTKT. The effectiveness of their biological functionalization was assessed via in vitro experiments with neural stem cells and their molecular assembly was elucidated via atomic force microscopy, Raman and FTIR spectroscopy. We demonstrated that glycine-spacers play a crucial role in the scaffold stability and in the exposure of the functional motifs. In particular, a glycine-spacer of four residues leads to a more stable nanostructure and to an improved exposure of the functional motif. Accordingly, the longer spacer of glycines, the more effective is the functional motif in both eliciting neural stem cells adhesion, improving their viability and increasing their differentiation. Therefore, optimized designing strategies of functionalized biomaterials may open, in the near future, new therapies in tissue engineering and regenerative medicine.

TL;DR: The risk model can use non-HLA risk factors for CD to improve identification of high-risk individuals with slight decrease in specificity and is a first step toward better diagnosis and prognosis in high- risk families and population-based screening.
