Haemophilus influenzae type b (Hib) is one of the leading causes of meningitis in developing countries. To establish and evaluate a novel loop-mediated isothermal amplification (LAMP) assay for Hib, we designed a LAMP primer set targeting the Hib-specific capsulation locus. LAMP detected 10 copies of purified DNA in a 60-min reaction. This indicated that the detection limit of LAMP was >100-fol...

BACKGROUND Sheep poxvirus (SPPV), Goat poxvirus (GTPV) and Lumpy skin disease virus (LSDV) are the most serious poxviruses of ruminants. They are double stranded DNA viruses of the genus Capripoxvirus, (subfamily Chordopoxvirinae) within the family Poxviridae. The aim of this study was to develop a Loop-mediated isothermal AMPlification (LAMP) assay for the detection of Capripoxvirus (CaPV) DNA...

Chaperone-mediated autophagy (CMA) is a selective mechanism for the degradation of soluble cytosolic proteins in lysosomes. The limiting step of this type of autophagy is the binding of substrates to the lysosome-associated membrane protein type 2A (LAMP-2A). In this work, we identify a dynamic subcompartmentalization of LAMP-2A in the lysosomal membrane, which underlies the molecular basis for...

Plant-based food ingredients such as garlic, Chinese leek, Chinese onion, green onion and onion are widely used in many cuisines around the world. However, these ingredients known as the "five forbidden vegetables" (FFVs) are not allowed in some vegetarian diets. In this study, a loop-mediated isothermal amplification (LAMP) assay was developed for the detection of FFVs using five respective LA...

The Lysosomal Associated Membrane Protein type-2 (LAMP-2) is an abundant lysosomal membrane protein with an important role in immunity, macroautophagy (MA) and chaperone-mediated autophagy (CMA). Mutations within the Lamp2 gene cause Danon disease, an X-linked lysosomal storage disorder characterized by (cardio)myopathy and intellectual dysfunction. The pathological hallmark of this disease is ...

A novel nucleic acid amplification method, termed loop-mediated isothermal amplification (LAMP), which amplifies DNA with high specificity, efficiency, and rapidity under isothermal conditions, may be a valuable tool for the rapid detection of infectious agents. LAMP was developed for human herpesvirus 6 (HHV-6), and its reliability was evaluated in this study. Although LAMP products were detec...

Melioidosis is a severe infection caused by Burkholderia pseudomallei. The timely implementation of effective antimicrobial treatment requires rapid diagnosis. Loop-mediated isothermal amplification (LAMP) targeting the TTS1 gene cluster was developed for the detection of B. pseudomallei. LAMP was sensitive and specific for the laboratory detection of this organism. The lower limit of detection...

Lamp 1 and lysosomal acid phosphatase (LAP) are lysosomal membrane proteins that harbour a tyrosine-based sorting motif within their short cytoplasmic tails. Lamp 1 is delivered from the trans-Golgi network (TGN) via endosomes directly to lysosomes bypassing the plasma membrane, whereas LAP is indirectly transported to lysosomes and recycles between endosomes and the plasma membrane before bein...
