β-D-Glucose-Reduced Silver Nanoparticles Remodel the Tumor Microenvironment in a Murine Model of Triple-Negative Breast Cancer.

Breast cancer is the most diagnosed type of cancer worldwide and the second cause of death in women. Triple-negative breast cancer (TNBC) is the most aggressive, and due to the lack of specific targets, it is considered the most challenging subtype to treat and the subtype with the worst prognosis. The present study aims to determine the antitumor effect of beta-D-glucose-reduced silver nanoparticles (AgNPs-G) in a murine model of TNBC, as well as to study its effect on the tumor microenvironment.

Exosomes isolated from IMMUNEPOTENT CRP, a hemoderivative, to accelerate diabetic wound healing.

The increasing risk of amputation due to diabetic foot ulcer calls for new therapeutic options; for that, we determined the role of IMMUNEPOTENT CRP (ICRP) and its parts in the wound healing process of superficial wounds in diabetic BALB/c mice. A potency test was performed to confirm the batch of ICRP, and then its parts were separated into pellets, supernatants, and exosomes, and another group of exosomes loaded with insulin was added. Viability and scratch healing were assessed in NIH-3T3, HUVEC, and HACAT cell lines.

Antibacterial efficacy of novel bismuth-silver nanoparticles synthesis on and infection models.

Introduction: The emergence of multi-drug-resistant bacteria is one of the main concerns in the health sector worldwide. The conventional strategies for treatment and prophylaxis against microbial infections include the use of antibiotics. However, these drugs are failing due to the increasing antimicrobial resistance.

Antitumor efficacy of silver nanoparticles reduced with β-D-glucose as neoadjuvant therapy to prevent tumor relapse in a mouse model of breast cancer.

Neoadjuvant therapy constitutes a valuable modality for diminishing tumor volume prior to surgical resection. Nonetheless, its application encounters limitations in the context of recurrent tumors, which manifest resistance to conventional treatments. Silver nanoparticles (AgNPs) have emerged as a promising alternative for cancer treatment owing to their cytotoxic effects.

Antitumoral and Immunogenic Capacity of β-D-Glucose-Reduced Silver Nanoparticles in Breast Cancer.

Immunogenic cell death (ICD) is a type of cell death capable of stimulating immunity against cancer through danger signals that lead to an adaptive immune response. Silver nanoparticles (AgNPs) have been shown to have a cytotoxic effect on cancer cells; however, their mechanism of action is not fully understood. The present study synthesized, characterized, and evaluated the cytotoxic effect of beta-D-glucose-reduced AgNPs (AgNPs-G) against breast cancer (BC) cells in vitro; and assess the immunogenicity of cell death in vitro and in vivo.

Design, Synthesis, and Evaluation of Peptides Derived from L1 Protein Against Bovine Papillomavirus-1/2 Identified Along Mexico's Cattle Export Route.

Introduction: Bovine papillomatosis affects animal health and represents one of the greatest economic losses in the livestock sector. New control and prevention methods to protect the livestock industry from this disease are necessary. The aim of this study was to evaluate a candidate peptide for antibody production against bovine papillomavirus (BPV).

Development of a new generation of miniemulsion based on cottonseed oil with α-tocopherol and ZnO and evaluation of its adjuvant activity.

Background: Emulsions have been widely used as immunological adjuvants. But the use of materials derived from plants such as cottonseed oil, alpha-tocopherol, or minerals such as zinc, as well as their use at the nanometric scale has been little explored. In this study, we develop a new miniemulsion and evaluated its antioxidant and phagocytic capacity, as well as parameters related to immune response stimulation by cytokine expression and antibodies production in a mice model.

chemosensitivity of a canine tumor venereal transmissible cancer cell line.

The canine transmissible venereal tumor (CTVT) is the most common malignity in dogs. Because there are reports that this tumor is resistant to vincristine sulfate, the chemotherapeutic options are scarce, and the development of new therapeutic approaches is necessary. In this study, we evaluated the cytotoxic activity of vincristine, doxorubicin, temozolomide, panobinostat, toceranib, gemcitabine, cisplatin, fluorouracil, cyclophosphamide, and methotrexate on a CTVT cell line, determining that all drugs decreased the viability in a dose-dependent manner.

Evaluation of the cytotoxic and immunogenic potential of temozolamide, panobinostat, and extract against C6 glioma cells.

Glioblastoma multiforme is a malignant neoplasm of the brain with poor prognosis. The first-line drug against glioblastoma is the alkylating agent temozolamide (TMZ); unfortunately, treatment resistance and tumor re-incidence are common. In some cases, immunogenic cell death (ICD) inducers can decrease treatment resistance and tumor recurrence by stimulating an antitumor specific immune response.
