Application

6-Biopterin is an oxidation product from the melanogenesis regulating cofactor (6R)5,6,7,8 tetrahydrobiopterin (6-BH4). In vitro, 6-Biopterin is cytotoxic to melanocytes. However, in vivo, 6-Biopterin is rapidly and sequentially reduced back to 6-GH4 via q-BH2. Recent studies suggest that 6-Biopterin among other pteridines may be a useful non-invasive biomarker for cancer.

Intracellular pathogens belonging to the genus Leishmania have developed effective strategies that enable them to survive within host immune cells. Immunostimulatory compounds that counteract such immunological escape mechanisms represent promising treatment options for diseases. Here, we demonstrate that a lipopeptidephosphoglycan

Polarization-resolved second-harmonic generation (PR-SHG) microscopy is described and applied to identify the presence of multiple crystallographic domains within protein-crystal conglomerates, which was confirmed by synchrotron X-ray diffraction. Principal component analysis (PCA) of PR-SHG images resulted in principal component 2 (PC2)

CXCL16 is a multifunctional chemokine that is highly expressed by macrophages and other immune cells in response to bacterial and viral pathogens; however, little is known regarding the role of CXCL16 during parasitic infections. The protozoan parasite Leishmania donovani is

Many RNA viruses are found in protozoan parasites. They can be responsible for more serious pathology or treatment failure. For the detection of viral double-stranded RNA (dsRNA), sequence-dependent and -independent methods are available, such as quantitative real-time PCR and immunofluorescence
