We previously described mRNA electroporation as an efficient gene delivery method to introduce tumor-antigens (Ag) into murine immature dendritic cells (DC). Here, we further optimize the protocol and evaluate the capacity of mRNA-electroporated DC as a vaccine for immunotherapy. First, the early DC maturation kinetics and the effect of different lipopolysaccharide incubation periods on the phenotypic maturation profile of DC are determined. Next, we show that either immature or mature DC are equally well electroporated and express and present the transgene at a comparable level after electroporation. We point out that the mRNA electroporation results in a negative effect on the interleukin (IL)-12p70, IL-6, and tumor necrosis factor-alpha secretion after maturation. Nevertheless, mRNA-electroporated DC induce an effective cytotoxic T lymphocyte (CTL) response in vivo. Mature electroporated DC are significantly more potent in eliciting an Ag-specific CD8+ CTL response compared to their immature electroporated counterparts. In addition, a significant improvement in CTL response is obtained both in the primary and in the memory effector phases when CD4+CD25+ regulatory T cells (Treg) are depleted in vivo prior to immunization. These findings are further substantiated in tumor protection experiments and hold convincing evidence for the merit of Treg cell depletion prior to immunization with mRNA-electroporated DC.

Endometrial collagen I undergoes dynamic degradation and remodelling in response to endometrial stromal cell (ESC) decidualization and embryo implantation. However, excessive collagen I deposition in the endometrium during the implantation window may impair decidualization, causing embryo implantation failure in patients with endometriosis (EMS). We found that endometrial collagen I expression during the mid-secretory phase was increased in the EMS group of patients.

The pathogenesis of necrotic enteritis (NE) involves complex gene regulation at both the bacterial cell and host tissue levels, yet many aspects remain incompletely understood. This study aims to compare the differential transcriptome of the netB-positive Clostridium perfringens strain, CP54, before and after infection. Differentially expressed genes and pathways were also examined in jejunal tissues from CP54-induced and CP54-Eimeria coinfected NE models to identify potential targets for mitigating NE.

The venom of Colombian specimens of the rear-fanged snake Pseudoboa neuwiedii contains proteolytic and phospholipase A (PLA) activities, but is devoid of esterases. Mass spectrometric analysis of electrophoretic bands indicated that this venom contains C-type lectins (CTL), cysteine-rich secretory proteins (CRiSP), PLA, snake venom metalloproteinases (SVMP), and snake venom matrix metalloproteinases (svMMP). In this investigation, we extended our characterization of P.

It has been established that essential amino acids (EAA) regulate protein synthesis in mammary epithelial cells by rapidly altering the phosphorylation state of translation factors. However, the long-term transcriptional response to EAA supply has been investigated much less. Eight transcription factors were selected as candidate mediators of EAA effects on mammary cell function via the amino acid response (ATF4, ATF6), mitogen-activated protein kinase (JUN, FOS, EGR1), and mechanistic target of rapamycin complex 1 (MYC, HIF1A, SREBF1).
