T-cell development depends upon interactions between thymocytes and thymic epithelial cells (TECs). The engagement of delta-like 4 (DL4) on TECs by Notch1 expressed by blood-borne BM-derived precursors is essential for T-cell commitment in the adult thymus. In contrast to the adult, the earliest T-cell progenitors in the embryo originate in the fetal liver and migrate to the nonvascularized fet...

Dendritic cells (DCs) induce pathogen-specific T cell responses. We comprehensively studied the effects of addition of maturation stimulus, fibroblasts (fibroblast conditioned medium), PHA activated T cells (T cell conditioned medium), and mixture of fibroblast & PHA activated T cells (FCM-TCCM) conditioned media on maturation of DCs. Monocytes were cultured with GM-CSF and IL-4 for five days. ...

A case of a primary peripheral T cell lymphoma arising in the endometrium is presented. Primary lymphomas of the female genital tract are rare, with endometrial lymphomas and those of T cell type being rarer still. Extensive investigations revealed no other sites of disease and the patient was treated by hysterectomy and chemotherapy. She remains well 33 months later. We believe that this case ...

BACKGROUND Cutaneous T-cell lymphoma (CTCL) can have a profound impact on a patient's health-related quality of life; however, little is known about its actual impact. The authors evaluated patients' perspectives on the impact of CTCL on physical functioning, lifestyle, emotional well being, and satisfaction with treatment. METHODS A 4-page, self-administered questionnaire was mailed and made...
