Intragenic antimicrobial peptide Hs02 toxicity against leukemia cell lines is associated with increased expression of select pyroptotic components.

The anticancer potential of some antimicrobial peptides has been reported. Hs02 is a recently characterized Intragenic Antimicrobial Peptide (IAP), which was able to exhibit potent antimicrobial and anti-inflammatory action. In this study, we evaluate for the first time the antineoplastic potential of the Hs02 IAP using cell lines representing the main types of leukemia as cancer models.

Resveratrol attenuates doxorubicin-induced toxicity during culture of mouse-isolated preantral follicles.

The aims of this study were to evaluate the doxorubicin concentration that induces toxic effects on culture of isolated mouse secondary follicles and to investigate whether resveratrol can inhibit or reduce this toxicity. Secondary follicles were isolated and cultured for 12 days in control medium (α-MEM) or in α-MEM supplemented with doxorubicin (0.1 µg/ml) or different concentrations of resveratrol (0.

Effect of iontophoresis on dacarbazine cutaneous delivery for melanoma topical treatment.

Dacarbazine (DTIC) is the drug of choice for melanoma treatment, but its systemic administration is related to several adverse effects. Here, DTIC topical delivery stimulated by iontophoresis is proposed to overcome such drawbacks. Hence, this work analyzed the impact of anodal iontophoresis on DTIC cutaneous delivery to provide an innovative topical alternative for melanoma treatment.

Role of the afferent lymph as an immunological conduit to analyze tissue antigenic and inflammatory load.

The lymphatic fluid is the conduit by which part of the tissue "omics" is transported to the draining lymph node for immunosurveillance. Following cannulation of the pre-nodal cervical and mesenteric afferent lymphatics, herein we investigate the lymph proteomic composition, uncovering that its composition varies according to the tissue of origin. Tissue specificity is also reflected in the dendritic cell-major histocompatibility complex class II-eluted immunopeptidome harvested from the cervical and mesenteric nodes.
