As showed in Figure 2, histological sections of the thymus revealed extensive melioration in LBP(H) group mice compared with model group mice. In the model group, the disruption of thymic architecture could be observed both in the generalized tissue as well as in the medullary region. Disruption of the medullary region could be vital for T cell development, as it is the principle region where mature thymocytes survive and accumulate. However, this damage was meliorated considerably by the LBP(H) treatment, and the thymus could allow a more stable environment for T cell development.
