PBMC-mediated modulation of macrophage polarization in RAW264.7 cells through STAT1/STAT6 signaling cascades.

Peripheral blood mononuclear cells (PBMC), sourced autologously, offer numerous advantages when procured: easier acquisition process, no in vitro amplification needed, decreased intervention and overall increased acceptability make PBMC an attractive candidate for cell therapy treatment. However, the exact mechanism by which PBMC treat diseases remains poorly understood. Immune imbalance is the pathological basis of many diseases, with macrophages playing a crucial role in this process.

Cynaropicrin disrupts tubulin and c-Myc-related signaling and induces parthanatos-type cell death in multiple myeloma.

The majority of blood malignancies is incurable and has unforeseeable remitting-relapsing paths in response to different treatments. Cynaropicrin, a natural sesquiterpene lactone from the edible parts of the artichoke plant, has gained increased attention as a chemotherapeutic agent. In this study, we investigated the effects of cynaropicrin against multiple myeloma (MM) cells in vitro and assessed its in vivo effectiveness in a xenograft tumor zebrafish model.

The acetic acid injection induced regional inflammation wound hyperpigmentation by recruiting pigment cells to the wound area.

Epimedin C Promotes Vascularization during BMP2-Induced Osteogenesis and Tumor-Associated Angiogenesis.

Epimedin C is one of the chemical markers and major flavonoids in Herba Epimedii (Yinyanghuo), which is traditionally used to treat bone diseases and gonadal dysfunction in China. Our previous study indicated that epimedin C could induce endothelial-like, but not osteogenic differentiation of C3H/10T1/2 cells in vitro. As vasculogenesis plays a pivotal role in bone formation, this study used the bone morphogenetic protein 2 (BMP2) induced ectopic bone formation model and mice 4T1 breast cancer cells co-implanted with luciferase labeled C3H/10T1/2 cells (4T1 [Formula: see text] C3H/10T1/2-Luc) model to examine the in vivo effects of Epimedin C on vasculogenesis.

Hydrophobicity-related protein contents and surface areas of aerial conidia are useful traits for formulation design of fungal biocontrol agents.

To clarify the potential use of hydrophobicity-related traits of aerial conidia in formulation design of fungal biocontrol agents, hydrophobicity rates (H (r)) and surface areas (S (a)) of aerial conidia were assessed with 48 strains of Beauveria bassiana, Isaria fumosorosea and Metarhizium spp. Inter- or intra-specific variation was large in H (r) (59.7-92.

A cell wall protein, CWP10, resolved from the conidial formic acid extract of a Metarhizium anisopliae isolate, was characterized as a new 9.9-kDa protein with a 32-aa signal peptide with a central hydrophobic region (ca. 10 residues) at its N-terminus.

[Comparative susceptibility of Myzus persicae to 16 strains of Metarhizium spp. from different host insects and geographic regions].

The fungal biocontrol agents Metarhizium species and varieties have been widely applied for insect control but their targets rarely aim at sucking-type homopteran insects such as aphids. To search for fungal candidates against aphids, 16 strains of four varieties of two Metarhizium species, most of which originally infected foliage insect pests in Asia, Africa and America, were bioassayed to compare their virulence to Myzus persicae apterae. With each strain, each of three conidial suspensions was sprayed onto aphids in three Petri dishes (about 40 aphids per dish) in a Potter Spray Tower, resulting in deposits of conidia for low, medium and high dosage treatments (no.
