Dendritic cells can be self sustaining
The authors have found that the two yeast mRNA capping enzymes, Cet1p and Ceg1p, are potent in vitro inhibitors of transcription. Cet1p, stimulated by its Ceg1p binding partner, stalled transcription by blocking reinitiation at already activated promoters. Conversely, elimination of Cet1p in vivo stimulated transcription. Although Cet1p is the first general repressor found to act at reinitiatio...
متن کاملSelf-sustaining Sub-populations of Progenitor Cells
It has been established in several types of cancers, that the growth and maintenance of many cancers is due to a (typically small) sub-population of cells with stem-like properties: cells which are capable of indefinite self-renewal and of giving rise to all the different types of cells present in the cancer. The origins of these stem-like cancer cells are not entirely clear, and it has not bee...
متن کاملHow can Alzheimer's Patients be Helped?
پرستاری از بیمار مبتلا به بیماری آلزایمر چندان ساده نیست. حتی اگر از این امر که اختلال رفتاری فرد نشانه ای از بیماری اوست، آگاه باشید، اکثر مواقع نمی دانید که چگونه باید با او رفتار کنید. در این مقاله روشهای مناسبی ارائه گردیده تا خانواده بیمار بتواند با ۱۰ اختلال رفتاری شایع در بیماران مبتلا بدون احساس ناامیدی و خشم سازگاری یابند.
متن کاملSkin-derived dendritic cells can mediate deletional tolerance of class I-restricted self-reactive T cells.
Skin-draining lymph nodes contain a number of dendritic cell (DC) subsets of different origins. Some of these are migratory, such as the skin-derived epidermal Langerhans cells and a separate dermal DC subset, whereas others are lymphoid resident in nature, such as the CD8+ DCs found throughout the lymphoid tissues. In this study, we examine the DC subset presentation of skin-derived self-Ag by...
متن کاملDendritic Cells in Transplant Tolerance
Dendritic cells (DCs) are a heterogeneous family of professional APCs involved in priming adaptive immune responses. Donor DCs (direct pathway of allorecognition) and recipient DCs presenting processed donor major histocompatibility complex (MHC) as peptides (indirect pathway of allorecognition) participate actively in graft rejection by stimulating recipient T cell responses following organ tr...
