The inventive technology relates to novel paratransgenic strategies for the biocontrol of pathogens in animal systems using interfering RNA molecules expressed in genetically modified bacteria that may be configured to colonize a target host. In one preferred embodiment, the invention includes novel paratransgenic strategies for the biocontrol of pathogens in aquatic organisms raised in aquaculture environments.

A composition for the controlled release of a nucleic acid such as short interfering RNA or messenger RNA,comprising silicon nanoparticles, at least one amino acid,and at least one lipid, wherein the silicon nanoparticles comprise at least 50% by weight silicon. Also related compositions and methods.

A red blood cell extracellular vesicle (RBCEV) loaded with a nucleic acid cargo; method for preparing the loaded vesicle; and the therapeutic use of the vesicle thereof are disclosed. The nucleic acid cargoes may be DNA or RNA, single stranded or double stranded, as well as linear or circular.

The disclosure is directed to dual variable domain immunoglobulin double-stranded RNA conjugates that are advantageous for inhibition of target gene expression, as well as compositions suitable for therapeutic use. The dual variable domain immunoglobulin comprises a first variable domain that binds to a binding target, and a second variable domain that comprises a reactive residue, where the linker is covalently conjugated to the reactive residue. The dsRNA is linked to the linker and is capable of inhibiting the expression of the target gene by RNA interference. The disclosure also provides pharmaceutical compositions comprising these conjugate and methods of inhibiting the expression of a target gene by administering these conjugates, e.g., for the treatment of various disease conditions.

Compositions and methods for transforming cells and generating transgenic grapevine plants comprising two silencing suppressor proteins C2 and V2 encoded by GRBV and recombinant hairpin vectors targeting C2 and V2, which are be used to generate stably transformed transgenic grapevine plants.

The present disclosure provides siRNA that suppresses proliferation of new coronaviruses (SARS-CoV-2). The siRNA disclosed herein includes: a sense strand; and an antisense strand. The sense strand includes a target sequence comprising 19 to 23 bases in which a base at a 5′ terminal is guanine (G) or cytosine (C), and an overhang comprising 2 to 4 bases added to a 3′ terminal side of the target sequence. The antisense strand includes a sequence complementary to the target sequence, and an overhang comprising 2 to 4 bases added to a 3′ terminal side of the complementary sequence. Here, at least a part of the target sequence contains at least a part of a base sequence encoding a signal peptide region of a spike protein (S protein) of SARS-CoV-2.
