|Oligos targeted to trigger nonsense-mediated decay (NMD)||
This paper provides some experimental support for targeting steric-blocking oligos to alter splicing and trigger nonsense-mediated decay. The paper compared uniform 2'-methoxyethyl phosphorothioate oligos with 2'-MOE phosphorothioate gapmers (steric blocking versus RNase-H competent, respectively).
Nonsense-mediated decay as a terminating mechanism for antisense oligonucleotides.

|Intranasal administration in mice of peptide-conjugated Morpholinos||
Peptide-conjugated Morpholinos were administered intranasally to mice to alter the immune response to subsequent intranasal influenza doses. "BALB/c mice were anesthetized with ketamine, followed by i.n. administration with 100 mg (approximately 5 mg/kg) PPMO (in 40 ml of PBS)." Repeat dosing at 24 hours, influenza inoculation at 48 hours.

|Knockdowns in mosquito guts||
Vivo-Morpholinos were fed to mosquitos. The oligos decreased the amount of MAPK protein in the midgut and the number of Plasmodium oocysts in the mudgut.
"The feeding protocol described in the present study provides several advantages over current methods for gene knockdown in insects. The method is easy to apply, requires no special skills for delivery, and is highly target specific. ... This protocol should therefore be considered as an efficient alternative in studies requiring target specific protein knockdown in mosquitoes and other arthropods."

|Morpholino electroporated into human T-cells induces alternative splicing without interferon response||
Michel M, Wilhelmi I, Schultz A-S, Preussner M, Heyd F. Activation-induced Tumor Necrosis Factor Receptor-associated Factor 3 (Traf3) Alternative Splicing Controls the Noncanonical Nuclear Factor κB Pathway and Chemokine Expression in Human T Cells. J Biol Chem. 2014;289:13651-60. doi:10.1074/jbc.M113.526269
"Furthermore, the interferon response, which can be regulated by Traf3 (35), was not altered in Traf3E8 MO-treated cells (data not shown)" supports that the Morpholino did not induce an innate immune response.
