Most studies on the docking of ivermectin on the spike protein of SARS-CoV-2 concern the receptor binding domain (RBD) and, more precisely, the RBD interface recognized by the ACE2 receptor. The N-terminal domain (NTD), which controls the initial attachment of the virus to lipid raft gangliosides, has not received the attention it deserves. In this study, we combined molecular modeling and physicochemical approaches to analyze the mode of interaction of ivermectin with the interface of the NTD-facing lipid rafts of the host cell membrane.

The Ebola virus (EBOV) causes severe disease in humans, and animal models are needed to evaluate the efficacy of vaccines and therapeutics. While non-human primate (NHP) and rodent EBOV infection models have been well characterized, there is a growing need for an intermediate model. Here, we provide the first report of a small-particle aerosol (AE) EBOV ferret model and disease progression compared with the intramuscular (IM) EBOV ferret model.

Nanodrug delivery systems have revolutionized tumor therapy like never before. By overcoming the complexity of the tumor microenvironment (TME) and bypassing drug resistance mechanisms, nanotechnology has shown great potential to improve drug efficacy and reduce toxic side effects. This review examines the impact of the TME on drug resistance and recent advances in nanomedicine delivery systems to overcome this challenge.

Cancer, the most common condition worldwide, ranks second in terms of the number of human deaths, surpassing cardiovascular diseases. Uncontrolled cell multiplication and resistance to cell death are the traditional features of cancer. The myriad of treatment options include surgery, chemotherapy, radiotherapy, and immunotherapy to treat this disease.
