Paper
The transcription factor BATF pioneers the differentiation program of effector CD8(+) T cells through the interaction with IRF4Cell reports · 2025
Summary (written by the submitters)
The transcription factor BATF plays critical roles in the differentiation of various immune cells, including CD8+ T cells. Here, we demonstrated that BATF controls epigenomic and transcriptomic reprogramming of CD8+ T cells at an early phase of acute viral infection, thereby promoting the differentiation of cytolytic effector CD8+ T cells.

Loss of BATF drastically perturbed gene expression, chromatin accessibility, and the bindings of key transcription factors including Jun, T-bet, and IRF4. The direct interaction with IRF4 was essential for BATF-mediated effector differentiation, as the BATF mutant lacking this interaction failed to induce proper chromatin remodeling and proliferation of antigen-specific CD8+ T cells. Notably, IRF4 binding was exhaustively dependent on BATF, whereas BATF retained binding capacity even in IRF4-deficient CD8+ T cells. Furthermore, BATF initiated chromatin remodeling in the absence of IRF4, whereas subsequent dynamic epigenomic reorganization required IRF4. Our data proposed that BATF serves as a “pioneer transcription factor” spearheading the reorganization of chromatin architecture upon antigen encounter, followed by further rearrangement of epigenomic and transcriptomic landscapes through the cooperation with IRF4.

3 · Start from the raw reads

Raw sequencing reads

The original FASTQ files, straight from the sequencer, held at ENA. Large, and you align them yourself, so only choose this if you need to re-process the study from scratch.

Raw reads on ENA ↗

What the files usually look like: Look for peak files (.bed, .narrowPeak) and signal tracks (.bigWig) among the supplementary files; the raw reads are on ENA.

Also filed as BioProject PRJNA1184146 and SRA study SRP544228. Searching any of these in the dataset finder brings you back here.
