Plasminogen is a 92-kDa single chain glycoprotein that circulates in plasma as a zymogen and when converted to proteolytically active plasmin dissolves preformed fibrin clots and extracellular matrix components. Here, we characterize the role of plasmin(ogen) in the complement cascade. Plasminogen binds the central complement protein C3, the C3 cleavage ...

Fusaricidins produced by Paenibacillus polymyxa DBB1709 are lipopeptide antibiotics active against fungi and Gram-positive bacteria. The cyclic hexapeptide structures of fusaricidins are synthesized by fusaricidin synthetase, a non-ribosomal peptide synthetase. The adenylation domain of the third module (FusA-A3) can recruit L: -Tyr, L: -Val, L: -Ile, L: -allo-Ile, or L: ...

The pHW126-like plasmids are a recently discovered small group of cryptic plasmids replicating by the rolling circle mode. The replication origin of pHW126 consists of a conserved stretch, four perfect direct repeats and a so called accessory region. The latter increases plasmid stability but is not absolutely necessary for replication. ...

Tetraspanins regulate a variety of cellular functions. However, the general cellular mechanisms by which tetraspanins regulate these functions remain poorly understood. In this article we collected the observations that tetraspanins regulate the formation and/or development of various tubular structures of cell membrane. Because tetraspanins and their associated proteins (1) are ...

An inter-helical acyl transfer specifically occurred between the C-and N-peptides of HIV gp41 after assembly of the six-helical bundle (6HB), forming an inter-helical covalent bond that greatly enhanced 6HB stability. In the reaction, the C-peptide was modified as an acyl donor, and the N-peptide served as an acyl acceptor.

Sestrin-2 is involved in p53-dependent antioxidant defenses and in the maintenance of metabolic homeostasis. We hypothesize that sestrin-2 expression is altered in the brains of subjects diagnosed with human immunodeficiency virus (HIV)-associated neurocognitive disorders (HAND) due to neuronal oxidative stress. We studied sestrin-2 immunoreactivity in 42 isocortex sections from HIV-1-infected ...

High-dose intravenous immunoglobulin (IVIG) therapy is the highly effective and standard treatment for Kawasaki disease (KD). However, ~20 % of KD patients have persistent fever or recurrence of fever after the initial IVIG treatment, which increases the risk for coronary artery lesions (CALs). Furthermore, the mechanism of IVIG resistance in KD ...

Chemotherapeutic agents such as paclitaxel applied in ultra-low, non-cytotoxic doses were previously shown to stimulate dendritic cell activity and anti-tumor immune responses upon vaccination in mouse transplantable tumor models. However, the mechanisms of these alterations-termed chemoimmunomodulation or chemomodulation-are still not clear. This study investigated the effect of paclitaxel applied in ...
