    Abstract: The present disclosure pertains to the recognition that immune responses mediated by CpG oligonucleotides can be affected by the stereochemistry of modified internucleotidic linkages such as phosphorothioates. In some embodiments, the present disclosure relates to chirally controlled CpG oligonucleotide compositions comprising CpG oligonucleotides comprising multiple modified internucleotidic linkages such as phosphorothioate linkages, wherein the oligonucleotides comprise one or more CpG region motifs having defined stereochemistry patterns of chiral internucleotidic linkages. In some embodiments, CpG oligonucleotides comprising one or more CpG region motifs are capable of agonizing an immune response. In some embodiments, CpG oligonucleotides comprising one or more CpG region motifs are antagonistic. Methods for making and using chirally controlled CpG oligonucleotide compositions are also described. In some embodiments, no immune modulation is desired, and the present disclosure provides methods of identifying chirally controlled oligonucleotide compositions which have decreased immune modulation.

    Abstract: Among other things, the present disclosure provides oligonucleotides, compositions, and methods thereof. Among other things, the present disclosure encompasses the recognition that structural elements of oligonucleotides, such as base sequence, chemical modifications (e.g., modifications of sugar, base, and/or internucleotidic linkages) or patterns thereof, conjugation with additional chemical moieties, and/or stereochemistry [e.g., stereochemistry of backbone chiral centers (chiral internucleotidic linkages)], and/or patterns thereof, can have significant impact on oligonucleotide properties and activities, e.g., knockdown ability, stability, delivery, etc. In some embodiments, the oligonucleotides decrease the expression, activity and/or level of a C9orf72 gene, including but not limited to, one comprising a repeat expansion, or a gene product thereof. In some embodiments, the present disclosure provides methods for treatment of diseases using provided oligonucleotide compositions, for example, in treatment of C9orf72-related disorders.

    Abstract: Among other things, the present disclosure provides technologies for altering splicing, particularly for increasing inclusion of exons in splicing products. In some embodiments, the present disclosure provides SMN2 oligonucleotides, compositions, and methods thereof. In some embodiments, the present disclosure provides chirally controlled SMN2 oligonucleotide compositions. In some embodiments, provided oligonucleotides and compositions can increase level of an exon 7-containing SMN2 splicing product and/or a gene product thereof. In some embodiments, the present disclosure provides methods for treatment of splicing-related conditions, disorders and diseases. In some embodiments, the present disclosure provides methods for treating SMN2-related conditions, disorders and diseases such as SMA (spinal muscular atrophy) and ALS (amyotrophic lateral sclerosis).
