Soluble isoforms of the DC-SIGN receptor can increase the dengue virus infection in immature dendritic cells.

Dengue is a disease with a high-impact on public health worldwide. Many researches have focused on the cell receptors involved in its pathogenesis. The role of soluble isoforms of DC-SIGN (Dendritic Cell-Specific ICAM-3 Grabbing Non-integrin) receptor in the process of Dengue Virus (DENV) infection is not well understood.

Compartmentalized Regulation of Pulmonary and Systemic Inflammation in Critical COVID-19 Patients.

Critical COVID-19 has been associated with altered patterns of cytokines. Distinct inflammatory processes in systemic and pulmonary sites have been reported, but studies comparing these two sites are still scarce. We aimed to evaluate the profile of pulmonary and systemic cytokines and chemokines in critically ill COVID-19 patients.

Dysfunctional phenotype of systemic and pulmonary regulatory T cells associate with lethal COVID-19 cases.

Severe cases of COVID-19 present hyperinflammatory condition that can be fatal. Little is known about the role of regulatory responses in SARS-CoV-2 infection. In this study, we evaluated the phenotype of regulatory T cells in the blood (peripheral blood mononuclear cell) and the lungs (broncho-alveolar) of adult patients with severe COVID-19 under invasive mechanical ventilation.

Biomarkers in Hypertension and Hypertension-related Disorders.

Systemic arterial hypertension (SAH) is a major risk factor for several secondary diseases, especially cardiovascular and renal conditions. SAH has a high prevalence worldwide, and its precise and early recognition is important to prevent the development of secondary outcomes. In this field, the study of biomarkers represents an important approach to diagnosing and predicting the disease and its associated conditions.

Frequency of germline genetic variants in women with a personal or family history of breast cancer from Brazil.

Background: About 5-10% of breast cancer cases are related to genetic and hereditary factors. The application of Next Generation Sequencing (NGS) in oncology has allowed the identification of genetic variants present in several genes related to the increased risk of breast cancer. This study aimed to determine the frequency of germline genetic variants in patients with a family and/or personal history of breast cancer.
