The information gap for children and young people with acquired brain injury

© 2019 The Author(s). Statement of Purpose This study explored the information requirements of children/youth with an acquired brain injury. Methods An on-line survey (n=16), focus group (n=5) and in-depth semi-structured interviews (n=3) elicited the views of 24 children/youth with ABI. A priori thematic coding was used to analyse the data. Results Five themes emerged: stage and age, school, friendship and peers, delivery methods and information content. The desired information changes over time depending on age and time since injury. Children/youth want their friends and teachers to access information on brain injury. Children/youth want information delivered through a range of channels, including videos (featuring genuine case studies), apps and board games. Children/youth wanted information specific to their injury, information on brain injury more generally, and practical strategies for overcoming problems. Conclusions Children/youth with ABI were able to express views about their information needs, which change over time and include a range of channels

The Action of Bax and Bcl-2 on T Cell Selection

T cell development and selection in the thymus are shaped by the induction of apoptosis. However, a direct role in T cell development and selection for any of the molecules known to regulate apoptosis has remained controversial. We have studied the effect of bax and bcl-2 transgenes in recombination activation gene 1–deficient (RAG-1−/−) mice transgenic for the major histocompatibility complex class I–restricted F5 T cell receptor. Overexpression of a bax transgene in the thymus seriously impairs the production of mature T cells, whereas bcl-2 overexpression greatly promotes it. The effect of bax and bcl-2 overexpression on antigen-induced negative selection was studied using fetal thymic organ cultures. This analysis showed that Bcl-2 strongly inhibits negative selection, whereas Bax does not affect it. Our data directly show that Bcl-2 family members have specific roles in T cell selection and also lend support to the hypothesis that Bax and Bcl-2 can antagonize each other's action in a certain apoptosis pathway while in another they can be functionally nonreciprocal

Mechanism of cellular rejection in transplantation

The explosion of new discoveries in the field of immunology has provided new insights into mechanisms that promote an immune response directed against a transplanted organ. Central to the allograft response are T lymphocytes. This review summarizes the current literature on allorecognition, costimulation, memory T cells, T cell migration, and their role in both acute and chronic graft destruction. An in depth understanding of the cellular mechanisms that result in both acute and chronic allograft rejection will provide new strategies and targeted therapeutics capable of inducing long-lasting, allograft-specific tolerance
