Conserved hemorrhagic fever virus genomic sequences

Conserved hemorrhagic fever virus genomic sequences are invariant segments of the RNA genomes found in viruses that cause viral hemorrhagic fevers (VHFs), such as Ebola, Marburg, and Lassa viruses [1.3.1]. These sequences typically reside within genes essential for the viral life cycle, including the RNA-dependent RNA polymerase (L gene), nucleoprotein (NP), and various viral proteins (VP24, VP35) that suppress host immune responses [1.3.2, 1.4.2]. Because these regions are highly conserved across different viral strains, they are prime targets for sequence-specific therapeutics like antisense oligonucleotides (ASOs) and small interfering RNAs (siRNAs) [1.3.3, 1.4.1]. These agents bind to the target sequences via Watson-Crick base pairing to either trigger RNA degradation or sterically block the translation of critical viral proteins [1.3.5]. Targeting these conserved sequences offers a strategy for developing broad-spectrum antivirals capable of treating highly pathogenic infections that often lack effective vaccines or standard treatments [1.4.3]. Therapeutic challenges include the potential for viral mutational escape and the need for efficient delivery systems, such as lipid nanoparticles, to reach target tissues like the liver and spleen [1.4.1, 1.4.3].
