Mice received morphine or saline perinatally, then were challenged with LPS or saline in adulthood, yielding four groups (SAL-SAL, SAL-LPS, MOR-SAL, MOR-LPS). NeuN+ neuronal nuclei (~10,000 per replicate) were isolated by FACS and profiled by MOWChIP-seq (Illumina NovaSeq X Plus, paired-end 150 nt). H3K27ac ChIP-seq identified differentially acetylated enhancers and promoters enriched in immune and metabolic pathways, with the hypothalamus exhibiting the most pronounced chromatin remodeling.</description><dates><publication>2026/06/17</publication></dates><accession>GSE332794</accession><cross_references><GSM>GSM9753519</GSM><GSM>GSM9753402</GSM><GSM>GSM9753523</GSM><GSM>GSM9753522</GSM><GSM>GSM9753401</GSM><GSM>GSM9753525</GSM><GSM>GSM9753404</GSM><GSM>GSM9753403</GSM><GSM>GSM9753524</GSM><GSM>GSM9753406</GSM><GSM>GSM9753527</GSM><GSM>GSM9753405</GSM><GSM>GSM9753526</GSM><GSM>GSM9753408</GSM><GSM>GSM9753529</GSM><GSM>GSM9753528</GSM><GSM>GSM9753407</GSM><GSM>GSM9753400</GSM><GSM>GSM9753521</GSM><GSM>GSM9753520</GSM><GSM>GSM9753509</GSM><GSM>GSM9753508</GSM><GSM>GSM9753512</GSM><GSM>GSM9753511</GSM><GSM>GSM9753514</GSM><GSM>GSM9753513</GSM><GSM>GSM9753516</GSM><GSM>GSM9753515</GSM><GSM>GSM9753518</GSM><GSM>GSM9753517</GSM><GSM>GSM9753510</GSM><GSM>GSM9753501</GSM><GSM>GSM9753500</GSM><GSM>GSM9753503</GSM><GSM>GSM9753502</GSM><GSM>GSM9753505</GSM><GSM>GSM9753504</GSM><GSM>GSM9753507</GSM><GSM>GSM9753506</GSM><GSM>GSM9753446</GSM><GSM>GSM9753567</GSM><GSM>GSM9753445</GSM><GSM>GSM9753566</GSM><GSM>GSM9753448</GSM><GSM>GSM9753569</GSM><GSM>GSM9753568</GSM><GSM>GSM9753447</GSM><GSM>GSM9753449</GSM><GSM>GSM9753440</GSM><GSM>GSM9753561</GSM><GSM>GSM9753560</GSM><GSM>GSM9753442</GSM><GSM>GSM9753563</GSM><GSM>GSM9753562</GSM><GSM>GSM9753441</GSM><GSM>GSM9753565</GSM><GSM>GSM9753444</GSM><GSM>GSM9753443</GSM><GSM>GSM9753564</GSM><GSM>GSM9753435</GSM><GSM>GSM9753556</GSM><GSM>GSM9753434</GSM><GSM>GSM9753555</GSM><GSM>GSM9753437</GSM><GSM>GSM9753558</GSM><GSM>GSM9753436</GSM><GSM>GSM9753557</GSM><GSM>GSM9753439</GSM><GSM>GSM9753559</GSM><GSM>GSM9753438</GSM><GSM>GSM9753550</GSM><GSM>GSM9753431</GSM><GSM>GSM9753552</GSM><GSM>GSM9753551</GSM><GSM>GSM9753430</GSM><GSM>GSM9753433</GSM><GSM>GSM9753554</GSM><GSM>GSM9753432</GSM><GSM>GSM9753553</GSM><GSM>GSM9753545</GSM><GSM>GSM9753424</GSM><GSM>GSM9753423</GSM><GSM>GSM9753544</GSM><GSM>GSM9753426</GSM><GSM>GSM9753547</GSM><GSM>GSM9753425</GSM><GSM>GSM9753546</GSM><GSM>GSM9753428</GSM><GSM>GSM9753549</GSM><GSM>GSM9753548</GSM><GSM>GSM9753427</GSM><GSM>GSM9753429</GSM><GSM>GSM9753420</GSM><GSM>GSM9753541</GSM><GSM>GSM9753540</GSM><GSM>GSM9753422</GSM><GSM>GSM9753543</GSM><GSM>GSM9753542</GSM><GSM>GSM9753421</GSM><GSM>GSM9753409</GSM><GSM>GSM9753413</GSM><GSM>GSM9753534</GSM><GSM>GSM9753412</GSM><GSM>GSM9753533</GSM><GSM>GSM9753536</GSM><GSM>GSM9753415</GSM><GSM>GSM9753414</GSM><GSM>GSM9753535</GSM><GSM>GSM9753417</GSM><GSM>GSM9753538</GSM><GSM>GSM9753416</GSM><GSM>GSM9753537</GSM><GSM>GSM9753419</GSM><GSM>GSM9753539</GSM><GSM>GSM9753418</GSM><GSM>GSM9753530</GSM><GSM>GSM9753411</GSM><GSM>GSM9753532</GSM><GSM>GSM9753531</GSM><GSM>GSM9753410</GSM><GSM>GSM9753480</GSM><GSM>GSM9753489</GSM><GSM>GSM9753482</GSM><GSM>GSM9753481</GSM><GSM>GSM9753484</GSM><GSM>GSM9753483</GSM><GSM>GSM9753486</GSM><GSM>GSM9753485</GSM><GSM>GSM9753488</GSM><GSM>GSM9753487</GSM><GSM>GSM9753479</GSM><GSM>GSM9753478</GSM><GSM>GSM9753471</GSM><GSM>GSM9753470</GSM><GSM>GSM9753473</GSM><GSM>GSM9753472</GSM><GSM>GSM9753475</GSM><GSM>GSM9753474</GSM><GSM>GSM9753477</GSM><GSM>GSM9753476</GSM><GSM>GSM9753468</GSM><GSM>GSM9753467</GSM><GSM>GSM9753469</GSM><GSM>GSM9753460</GSM><GSM>GSM9753462</GSM><GSM>GSM9753461</GSM><GSM>GSM9753464</GSM><GSM>GSM9753463</GSM><GSM>GSM9753466</GSM><GSM>GSM9753465</GSM><GSM>GSM9753457</GSM><GSM>GSM9753578</GSM><GSM>GSM9753456</GSM><GSM>GSM9753577</GSM><GSM>GSM9753459</GSM><GSM>GSM9753579</GSM><GSM>GSM9753458</GSM><GSM>GSM9753570</GSM><GSM>GSM9753451</GSM><GSM>GSM9753572</GSM><GSM>GSM9753571</GSM><GSM>GSM9753450</GSM><GSM>GSM9753453</GSM><GSM>GSM9753574</GSM><GSM>GSM9753452</GSM><GSM>GSM9753573</GSM><GSM>GSM9753455</GSM><GSM>GSM9753576</GSM><GSM>GSM9753454</GSM><GSM>GSM9753575</GSM><GSM>GSM9753390</GSM><GSM>GSM9753392</GSM><GSM>GSM9753391</GSM><GSM>GSM9753394</GSM><GSM>GSM9753393</GSM><GSM>GSM9753396</GSM><GSM>GSM9753395</GSM><GSM>GSM9753398</GSM><GSM>GSM9753397</GSM><GSM>GSM9753399</GSM><GSM>GSM9753381</GSM><GSM>GSM9753380</GSM><GSM>GSM9753383</GSM><GSM>GSM9753382</GSM><GSM>GSM9753385</GSM><GSM>GSM9753384</GSM><GSM>GSM9753387</GSM><GSM>GSM9753386</GSM><GSM>GSM9753389</GSM><GSM>GSM9753388</GSM><GSM>GSM9753491</GSM><GSM>GSM9753490</GSM><GSM>GSM9753379</GSM><GSM>GSM9753493</GSM><GSM>GSM9753492</GSM><GSM>GSM9753374</GSM><GSM>GSM9753495</GSM><GSM>GSM9753494</GSM><GSM>GSM9753376</GSM><GSM>GSM9753497</GSM><GSM>GSM9753496</GSM><GSM>GSM9753375</GSM><GSM>GSM9753499</GSM><GSM>GSM9753378</GSM><GSM>GSM9753377</GSM><GSM>GSM9753498</GSM><GPL>34290</GPL><GSE>332794</GSE><taxon>Mus musculus</taxon></cross_references></HashMap>
