Here we show that the cell-cycle regulator p21 is involved in immune system function. T lymphocytes from p21 −/− mice exhibit significant proliferative advantage over wild-type cells following ...

Sep. 18, 2024 — It is crucial for organisms to be able to control which genes are expressed in which cells and when. Naturally occurring chemical modifications of DNA-binding histone proteins ...

19, 2024 — Scientists are now able to directly compare the different kinds of injury that mechanical ventilation causes to cells in the lungs. In a new study, using a ventilator-on-a-chip model ...

Dendritic cells (DCs) act as gatekeepers between immunity and tolerance. Initially, it was postulated that mature DCs promote effector T cell responses and immature DCs promote tolerance.

Thymic atrophy, which substantially affects T-cell-dependent immune function, shifts immune response towards a humoral response. Estrogen has multiple actions in the immune system, creating clear ...

[7] Increased autoimmunity appears to be primarily the result of the combined effects of the reduction in naive T cells (produced by thymus involution) in concert with an activation of self ...

工业中的通讯要求与办公环境有着天壤之别。要考虑到通讯中的每一方面，比如网络中的主动和被动元件，终端设备，网络 ...
