BACKGROUND Apolipophorin-III (ApoLp-III) is known to play an important role in lipid transport and innate immunity in lepidopteran insects. However, there is no evidence of involvement of ApoLp-IIIs in the immune responses of dipteran insects such as Drosophila and mosquitoes. METHODOLOGY/PRINCIPAL FINDINGS We report the molecular and functional(More)
Peptidoglycan recognition proteins (PGRPs) are a family of innate immune molecules that recognize bacterial peptidoglycan. PGRP-LE, a member of the PGRP family, selectively binds to diaminopimelic acid (DAP)-type peptidoglycan to activate both the immune deficiency (Imd) and proPhenoloxidase (proPO) pathways in insects. A PGRP-LE-dependent induction of(More)
CD63, a member of the tetraspanin membrane protein family, plays a pivotal role in cell growth, motility, signal transduction, host-pathogen interactions and cancer. In this work, the cDNA encoding CD63 homologue (TmCD63) was cloned from larvae of a coleopteran beetle, Tenebrio molitor. The cDNA is comprised of an open reading frame of 705 bp, encoding(More)
The chitinase gene of baculoviruses is expressed in the late phase of virus replication in insects and possesses high exo- and endochitinase activity, which can hydrolyze chitin in the body of the insect, thus promoting terminal host liquefaction. Alphabaculovirus viral chitinases (vChitA) have been well analyzed, but information regarding viral chitinases(More)
Cactin was originally identified as an interactor of the Drosophila IκB factor Cactus and shown to play a role in controlling embryonic polarity and regulating the NF-κB signaling pathway. While subsequent studies have identified the roles for Cactin in the mammalian immune response, the immune function of Cactin in insects has not been described yet. Here,(More)
The 14-3-3 family of phosphorylated serine-binding proteins acts as signaling molecules in biological processes such as metabolism, division, differentiation, autophagy, and apoptosis. Herein, we report the requirement of 14-3-3ɛ isoform from Tenebrio molitor (Tm14-3-3ɛ) in the hemocyte antimicrobial activity. The Tm14-3-3ɛ transcript is 771 nucleotides in(More)
Autophagy is a process that is necessary during starvation, as it replenishes metabolic precursors by eliminating damaged organelles. Autophagy is mediated by more than 35 autophagy-related (Atg) proteins that participate in the nucleation, elongation, and curving of the autophagosome membrane. In a pursuit to address the role of autophagy during(More)
Freshwater molluscs have found strategic applications in public and veterinary health. Additionally, they have been used as bioindicator organisms towards environmental biomonitoring of polluted waters. The freshwater pulmonate, Physa acuta has been extensively studied as a potential biomarker in aquatic habitats with heavy metal, chemical, and microbial(More)
Electrical discharge using a capacitance of 450 μF at 7.0 and 8.0 kJ input energies was applied to mechanical alloyed Ti5Si3 powder without applying any external pressure. A solid bulk of nanostructured Ti5Si3 with no compositional deviation was obtained in times as short as 159 μsec by the discharge. During an electrical discharge, the heat generated is(More)
Regrettably, the original version of the article (10.1007/ s13258-015-0334-x) contains a minor error in the first name of one of the authors: Je Bong Lee should be corrected to Jae Bong Lee. The correct name is now updated in the article and also shown in this erratum.
