Este trabajo muestra que mirar solo los genes deja afuera información valiosa sobre los receptores, y que combinar ambos datos sin cuidado puede distorsionar las conclusiones. Para la medicina, eso quiere decir que los estudios futuros sobre inmunidad podrían ser más precisos. El resultado es metodológico, así que su impacto llega indirectamente a los pacientes.","quienFirma":"bioRxiv (preprint sin revisión por pares; institución de los autores no identificada en el resumen)","confianza":"preprint","consulta":null},"sello":{"hash":"e00fa16bb8f786330d3489c00ca655feba5ff3242fb365e1aaf43c3c2a58c2e4","sello":"1c97ba9af7e8ff3bee578d26c79bdd4f5b0fa48944e1dd6caa02478c24a75551","beacon":{"drand":{"cadena":"8990e7a9aaed2ffed73dbd7092123d6f289930540d7651336225dc172e51b2ce","ronda":6575956,"aleatorio":"2a57a8658c1d539864cc4ae3efbab33cd3270e814e75bf7846346721462f12e7","tiempo":"2026-10-22T22:55:00.000Z"},"nist":{"cadena":2,"pulso":1995177,"salida":"44471E1C8A000FA428D45A5C480CB1AAB6429BD43B19D16210510F8146BBA7769584FA09251B999E8D0B2F0EEC2EEEC53219499677294EE43E94C8610586BE7D","tiempo":"2026-10-22T22:54:00.000Z"},"noAntes":"2026-10-22T22:55:00.000Z"},"verificacion":{"drand":true,"nist":true},"tsa":{"time":"Oct 22 22:55:02 2026 GMT","provider":"freetsa.org","sobre":"sello"},"original":{"titulo":"Cell-level integration of gene expression and B cell receptor data captures complementary B cell information","descripcion":"Single-cell B cell analyses commonly define relationships among cells using gene expression (GEX), although paired B cell receptor (BCR) sequences provide complementary information about receptor features, differentiation, and clonal relationships. We evaluated multiple approaches for integrating paired GEX and BCR data into cell-level representations and compared their ability to capture complementary aspects of B cell biology. We compared BCR representations based on language-model embeddings and engineered sequence features across multiple integration strategies. Spaces dominated by BCR language-model embeddings captured broad sequence and clonal information but could distort cell type re","pubDate":"2026-10-22","url":"https://www.biorxiv.org/content/10.64898/2026.10.16.759689v1?rss=1"},"indexado":"2026-10-22T22:54:28.111Z"}}
