Engineered extracellular vesicles enriched with the miR‐214/199a cluster enhance the efficacy of chemotherapy in ovarian cancer

Molecular Oncology, EarlyView.
Loss of the miR‐214/199a cluster is associated with recurrence in ovarian cancer. Engineered small extracellular vesicles (m214‐sEVs) elevate miR‐214‐3p/miR‐199a‐5p in tumor cells, suppress β‐catenin, TLR4, and YKT6 signaling, reprogram tumor‐derived sEV cargo, reduce chemoresistance and migration, and enhance carboplatin efficacy and survival in ...

Metastasis on pause: How dormant tumor cells stay hidden within the tumor microenvironment and evade immune surveillance

Molecular Oncology, EarlyView.
Dormant cancer cells can hide in distant organs for years, evading treatment and the immune system. This review highlights how signals from the surrounding tissue and immune environment keep these cells inactive or trigger their reawakening. Understanding these mechanisms may help develop therapies to eliminate or control dormant cells and prevent ...

How Flagellin and Toll-Like Receptor 5 Contribute to Enteric Infection [PDF]

Infection and Immunity, 2007
Resistance to infection in vertebrates relies on a complex interaction between two separate but complementary arms of the immune system: adaptive immunity and innate immunity. Adaptive immunity refers to the recognition of specific molecular epitopes by either T or B lymphocytes and the ...

Identification of functional murine mitochondrial formyl peptides and their effects on myeloid‐derived suppressor cell generation

FEBS Open Bio, EarlyView.
We first identified functional murine mitochondrial N‐formyl peptides (MT‐FPs) and investigated their effects on the in vitro myeloid‐derived suppressor cell (MDSC) generation from bone marrow cells. We demonstrated that MT‐FPs acted directly on bone marrow cells to promote MDSC generation and modulated the polymorphonuclear (PMN)‐MDSC/monocyte (M ...

Activation of Toll-Like Receptor 5 Immune Signaling by HMGB1 [PDF]

Biophysical Journal, 2016
Human High Mobility Group Box-1 (HMGB-1) is an ubiquitously expressed nuclear protein which primarily functions as an architectural chromatin binding factor that binds to DNA in a structure specific manner. Recently, it has been linked to the pathogenesis of several inflammatory diseases regulating the innate immune system by two specific toll-like ...

Cyclic azapeptide CD36 ligand attenuates cardiac injury and reduces long‐chain fatty acid accumulation after myocardial ischemia–reperfusion in mice

FEBS Open Bio, EarlyView.
In a murine model of myocardial ischemia and reperfusion (MI/R), the CD36 azapeptide ligand MPE‐298 reduces cardiac injury and transiently lowers left ventricular long‐chain fatty acids (LCFAs) accumulation 3 h after reperfusion, accompanied by a decrease of oxidative stress and inflammation‐associated genes' expression in the heart and adipose tissue.

Innate immune activation in experimental autoimmune myocarditis [PDF]

, 2007
Dilated cardiomyopathy (DCM) is a leading cause of heart failure and frequently results from postinfectious autoimmunity. Its pathophysiology is modeled by experimental autoimmune myocarditis (EAM), a CD4+ T-cell mediated murine model of ...

Helicobacter pyloriInduces Interleukin-8 Secretion by Toll-Like Receptor 2- and Toll-Like Receptor 5-Dependent and -Independent Pathways [PDF]

Infection and Immunity, 2005
ABSTRACTHelicobacter pyloriis an important human pathogen that causes gastritis and is strongly associated with gastric ulcers, gastric adenocarcinomas, and mucosa-associated lymphoid tissue lymphomas. In response toH. pylori, interleukin-8 (IL-8) is secreted from host cells to attract components of the innate and adaptive immune systems to the site of
