To do so, we developed two essential complimentary tools, a P. berghei antigen library in EL4 cells suited for class I MHC haplotype H-2b presentation and a reporter cell line, LR-BSL8.4a, that expresses α and β chains of the TCR derived from FACS-sorted, clonally expanded brain-sequestered T cells.
If so, Au. sediba's brain and pelvis would have both begun to evolve into more modern shapes before the brain expanded countering the view that the expanding brain drove the remodeling of the pelvis to accommodate bigger-brained babies.
Failing to maintain exposure to new challenges will ultimately fail to build or expand brain matter in the same way.

Regarding trauma of healthy mature brain tissue, programmed cell death can result from various mechanic and toxic insults and also disease, including expanding brain cancer.
