About half of the world's population is in danger because of the estimated 390 million infections and 96 million symptomatic cases that occur each year. An effective treatment for dengue fever (DF) does not yet exist. Therefore, a better knowledge of how viral proteins and virus-targeted medicines may exert distinct functions depending on the exact cellular region addressed may aid in creating much-needed antiviral medications. Lipids facilitate the coordination of many viral replication phases, from entrance to dissemination. In addition, flaviviruses masterfully plan a significant rearrangement of the host cell's lipid metabolism to foster the growth of new viruses. Recent research has consistently shown the significance of certain lipid classes in flavivirus infections. For instance, in DENV-infected cells, overall cellular cholesterol (CHO) levels are only a little altered, and DENV replication is significantly reduced when CHO metabolism is inhibited. Moreover, statins significantly decrease DENV serotype 2 (DENV-2) titers, indicating that CHO is a prerequisite for the dengue viral cycle. Furthermore, many Proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors are now being evaluated in human research. A new pharmacological target for the management of high CHO is PCSK9. Moreover, suppression of PCSK9 has been proposed as a possible defense against DENV. Numerous studies have generally recommended the use of lipid-lowering medications to suppress the DENV. As a result, we have investigated the DENV and popular treatment techniques in this research. We have also examined how lipid metabolism, cellular lipids, and lipid receptors affect DENV replication regulation.

By 2019, approximately 296 million individuals were chronically infected with HBV, with 1.5 million new cases annually and 820,000 deaths due to HBV-related cirrhosis and liver cancer. Current treatments for chronic hepatitis B include nucleotide analogs (NAs) and interferons (IFNs), particularly IFN-α. NAs, such as entecavir and tenofovir, inhibit viral reverse transcription, while IFN-α exerts antiviral effects by directly suppressing viral replication, modulating viral genome epigenetics, degrading cccDNA, and activating immune responses. Despite its potential, IFN-α shows limited clinical efficacy, partly due to HBV's interference with the IFN signaling pathway. HBV encodes proteins like HBc, Pol, HBsAg, and HBx that disrupt IFN-α function. For example, HBV Pol inhibits STAT1 phosphorylation, HBsAg suppresses STAT3 phosphorylation, and HBx interferes with IFN-α efficacy through multiple mechanisms. Additionally, HBV downregulates key genes in the IFN signaling pathway, further diminishing IFN-α's antiviral effects. Understanding these interactions is crucial for improving IFN-α-based therapies. Future research may focus on overcoming HBV resistance by targeting viral proteins or optimizing IFN-α delivery.
