Immunogenic amino acid motifs and linear epitopes of COVID-19 mRNA vaccines.
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8428655
PloS One; Wisnewski AV, Redlich CA et. al.

Sep 10th, 2021 - Reverse vaccinology is an evolving approach for improving vaccine effectiveness and minimizing adverse responses by limiting immunizations to critical epitopes. Towards this goal, we sought to identify immunogenic amino acid motifs and linear epitopes of the SARS-CoV-2 spike protein that elicit IgG in COVID-19 mRNA vaccine recipients. Paired pre/post vaccination samples from N = 20 healthy adul...

PloS One; Kulkarni R, Chen WC et. al.

Sep 10th, 2021 - COVID-19 in humans is caused by Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) that belongs to the beta family of coronaviruses. SARS-CoV-2 causes severe respiratory illness in 10-15% of infected individuals and mortality in 2-3%. Vaccines are urgently needed to prevent infection and to contain viral spread. Although several mRNA- and adenovirus-based vaccines are highly effective...

Sep 9th, 2021 - Global containment of COVID-19 still requires accessible and affordable vaccines for low- and middle-income countries (LMICs). Recently approved vaccines provide needed interventions, albeit at prices that may limit their global access. Subunit vaccines based on recombinant proteins are suited for large-volume microbial manufacturing to yield billions of doses annually, minimizing their manufac...

Chest Gable AD, Hughes SM et. al.

Sep 8th, 2021 - A 24-year-old man, never smoker, with no medical or surgical history, not currently on medications, presented to the ED with a second episode of gross hemoptysis, 4 months after an initial episode that had not previously been evaluated. He described the current episode of hemoptysis as "enough to fill the sink"; however, he did not further quantify. He has no history of recurrent epistaxis, hem...

Sep 7th, 2021 - Covid-19 has the respiratory tract as the main target of infection, and patients present mainly dyspnea, pneumonia, dry cough, and fever. Nevertheless, organs outside the respiratory tract had been reported in recent studies, including the gastrointestinal tract and liver. The host innate immune system recognizes pathogen-associated molecular patterns (PAMPs) through their pattern recognition r...

Proceedings of the National Academy of Sciences of the Un... Melvin WJ, Audu CO et. al.

Sep 5th, 2021 - COVID-19 induces a robust, extended inflammatory "cytokine storm" that contributes to an increased morbidity and mortality, particularly in patients with type 2 diabetes (T2D). Macrophages are a key innate immune cell population responsible for the cytokine storm that has been shown, in T2D, to promote excess inflammation in response to infection. Using peripheral monocytes and sera from human ...

Anticancer Research; Koike K, Nishiyama K et. al.

Sep 4th, 2021 - The role of tumour-infiltrating CD45Ro+ T-cells in oral squamous cell carcinoma (OSCC) is unclear. This study aimed to evaluate prognostic biomarkers for OSCC. We determined the density of tumour-infiltrating CD45Ro+ T cells in the parenchyma and stroma at the tumour centre (TCe) and invasive front (IF) and examined the association between the density of these cells and histopathological status...

Anticancer Research; VON Hoerschelmann E, Neumann CCM et. al.

Sep 4th, 2021 - Pancreatic ductal adenocarcinoma (PDAC) shows poor survival and early systemic dissemination. Cancer associated fibroblasts (CAFs) enhance migration and invasion of cancer cells. We aimed to investigate the role of CAFs in cell migration and their underlying paracrine effects. Using Transwell® migration assays, PDAC cells (PANC-1) and three distinct types of fibroblasts were analyzed: CAFs, gen...

Medicine Wang L, Wang H et. al.

Sep 4th, 2021 - The treatment for squamous cell lung cancer (SqCLC) is limited, and the prognosis of SqCLC is poor. In this article, we aimed to analyze and identify immune-related cells and competition endogenous RNA (ceRNA) that influence the prognosis of SqCLC. SqCLC and lung adenocarcinoma data were downloaded from TCGA-GDC. A total of 22 types of immune cell fractions were estimated using CIBERSORT. R sof...
