Chikungunya virus (CHIKV) is an Alphavirus (Togaviridae) responsible for Chikungunya fever (CHIKF) that is mainly characterized by a severe polyarthralgia, in which it is transmitted by the bite of infected Aedes aegypti and Ae. albopictus mosquitoes. Nowadays, there are no licensed vaccines or approved drugs to specifically treat this viral disease. Structural viral proteins participate in key steps of its replication cycle, Read More

Due to its fast international spread and substantial mortality, the coronavirus disease COVID-19 evolved to a global threat. Since there is currently no causative drug against this viral infection available, science is striving for new drugs and other approaches to treat the new disease. Studies have shown that the cell entry of coronaviruses into host cells takes place through the binding of the viral spike (S) protein to cell recept Read More

Outbreaks due to Severe Acute Respiratory Syndrome-Corona virus 2 (SARSCoV- 2) initiated in Wuhan city, China, in December 2019 and continued to spread Internationally, posing a pandemic threat as declared by WHO and as of March 10, 2021, confirmed cases reached 118 million along with 2.6 million deaths worldwide. In the absence of specific antiviral medication, symptomatic treatment and physical isolation remain the o Read More

COVID-19 is an infectious disease caused by SARS-CoV-2. The life cycle of SARS-CoV-2 includes the entry into the target cells, replicase translation, replicating and transcribing genomes, translating structural proteins, assembling and releasing new virions. Entering host cells is a crucial stage in the early life cycle of the virus, and blocking this stage can effectively prevent virus infection. SARS enters the target cells mediated by t Read More

Type l enveloped viruses bind to cell receptors through surface glycoproteins to initiate infection or undergo receptor-mediated endocytosis and initiate membrane fusion in the acidic environment of endocytic compartments, releasing genetic material into the cell. In the process of membrane fusion, envelope protein exposes fusion peptide, followed by an insertion into the cell membrane or endosomal membrane. Read More

Dengue virus (DENV) disease has become one of the major challenges in public health. Currently, there is no antiviral treatment for this infection. Since human transmission occurs via mosquitoes of the Aedes genus, most efforts have been focused on the control of this vector. However, these control strategies have not been totally successful, as reflected in the increasing number of DENV infections per year, becoming an end Read More

Cancer remains a deadly disease, and its treatment desperately needs to be managed through novel, rapidly advancing strategies. Most cancer cases eventually develop into recurrences, for which cancer stem cells (CSCs) are thought to be responsible. These cells are considered a subpopulation of all tumor cancer cells, with aberrant regulation of self-renewal, unbalanced proliferation, and cell death properties. CS Read More
