The Dichotomous Pattern of IL-12R and IL-23R Expression Elucidates the Role of IL-12 and IL-23 in Inflammation

IL-12 and IL-23 cytokines respectively drive Th1 and Th17 type responses. Yet, little is known regarding the biology of these receptors. As the IL-12 and IL-23 receptors share a common subunit, it has been assumed that these receptors are co-expressed. Surprisingly, we find that the expression of each of these receptors is restricted to specific cell types, in both mouse and human. Indeed, although IL-12Rβ2 is expressed by NK cells and a subset of γδ T cells, the expression of IL-23R is restricted to specific T cell subsets, a small number of B cells and innate lymphoid cells. By exploiting an IL-12- and IL-23-dependent mouse model of innate inflammation, we demonstrate an intricate interplay between IL-12Rβ2 NK cells and IL-23R innate lymphoid cells with respectively dominant roles in the regulation of systemic versus local inflammatory responses. Together, these findings support an unforeseen lineage-specific dichotomy in the in vivo role of both the IL-12 and IL-23 pathways in pathological inflammatory states, which may allow more accurate dissection of the roles of these receptors in chronic inflammatory diseases in humans

Enfermagem e genética: uma crítica feminista rumo ao trabalho em equipes transdisciplinares Nursing and genetics: a feminist critique moves us towards transdisciplinary teams

A informação genética e as tecnologias são cada vez mais importantes no cuidado em saúde, não somente nos países desenvolvidos, mas no mundo todo. Vários fatores globais prometem aumentar a futura demanda para pesquisa e serviços de saúde em genética moralmente conscientes. Embora os enfermeiros sejam o maior grupo profissional, prestando cuidado de saúde no mundo todo, eles não tomaram a liderança rumo a esse desafio. Insights, a partir da análise feminista, ajudam a esclarecer algumas das relações sociais e dos obstáculos culturais que têm impedido a integração da tecnologia genética na área da enfermagem. Um modelo alternativo é sugerido - o modelo transdisciplinar -, o qual foi desenvolvido inicialmente por uma enfermeira e introduzido, na década de 1970, na prestação do cuidado em saúde e no serviço social para crianças com déficit de desenvolvimento. Esse modelo holístico permite que todo profissional de saúde tenha a mesma voz ao determinar como o cuidado de saúde em genética será globalizado.<br>Genetic information and technologies are increasingly important in health care, not only in technologically advanced countries, but world-wide. Several global factors promise to increase future demand for morally conscious genetic health services and research. Although they are the largest professional group delivering health care world-wide, nurses have not taken the lead in meeting this challenge. Insights from feminist analysis help to illuminate some of the social institutions and cultural obstacles that have impeded the integration of genetics technology into the discipline of nursing. An alternative model is suggested - the transdisciplinary model - which was developed initially by a nurse and introduced in the 1970s into the delivery of health care and social services for children with developmental disabilities. This holistic model enables all health care professionals to have an equal voice in determining how genetic health care will be globalized
