sTNFR2 Revealed as a Novel Diagnostic Biomarker for Acute ATL

Adult T-cell leukemia/lymphoma (ATL) is a mature T-cell neoplasm associated with human T-cell leukemia virus type 1 (HTLV-1). Although only about 5% of HTLV-1 carriers progress to ATL, early diagnosis is challenging because of the lack of ATL biomarkers. Soluble tumor necrosis factor 2 (sTNFR2) is a novel and promising diagnostic biomarker for acute ATL. More...

Ultra-Fast Cycling for Multiplexed Cellular Fluorescence Imaging

In the treatment of tumors, microenvironment plays an important role. It often contains immune cells that are so changed that they promote tumor growth. Until now, analyses of these dynamic changes with conventional biopsies and tissue sections could take days to weeks, or not occur at all prior to treatment. More...

Deep Throat SARS-CoV-2 Viral Load Ascertained in Saliva Samples

Posterior oropharyngeal saliva samples are a non-invasive specimen more acceptable to patients and health-care workers. Unlike severe acute respiratory syndrome, patients with COVID-19 had the highest viral load near presentation, which could account for the fast-spreading nature of this epidemic. More...

Molecule in Lymphatic System Implicated in Autoimmune Diseases

A healthy immune system defends the body against diseases and infection. When someone has an autoimmune disease, the immune system malfunctions and the body mistakenly attacks healthy cells, tissues and organs. Rheumatoid arthritis, lupus and scleroderma are examples of autoimmune diseases. More...

Factors Associated with ARDS in COVID-19 Identified

 Patients with COVID-19 present primarily with fever, myalgia or fatigue, and dry cough. Although most patients are thought to have a favorable prognosis, older patients and those with chronic underlying conditions may have worse outcomes. More...

SARS-Cov-2 Specific Antibody Responses in COVID-19 Patients

 The rapid identification of the etiology and the sharing of the genetic sequence of the virus, followed by international collaborative efforts initiated due to the emergence of SARS-CoV-2 have led to the rapid availability of real-time PCR diagnostic assays that support the case ascertainment and tracking of the outbreak. More...

Image: Sacroiliac joint biopsy specimen of a 29 year old male patient with ankylosing spondylitis. The biopsy specimen shows a subchondral cellular infiltrate partly invading the cartilage. Fibroblasts and activated lymphocytes are seen in the infiltrate. In between are areas of calcification and bone formation (Photo courtesy of Professor J. Braun).

Fibrinogen-Albumin Ratio Correlated to Ankylosing Spondylitis Disease Activity

 Ankylosing spondylitis (AS) is a systematic inflammatory autoimmune disease that primarily involves the spine and sacroiliac joints. Typically the joints where the spine joins the pelvis are also affected and occasionally other joints such as the shoulders or hips are involved. Back pain is a characteristic symptom of AS, and it often comes and goes. More...
