The HLA region encodes several molecules that play key roles in the immune system. The advances being made in determining the primary associations within the HLA region and AIDs will not only increase our understanding of the mechanisms behind disease pathogenesis but may also aid in the development of novel therapeutic targets in the future. These diseases are often chronic and debilitating and, although treatments are available, many are inadequate [ 1 ] providing the impetus for a greater understanding of the disease mechanisms and the development of novel therapeutic agents.

The HLA Region and Autoimmune Disease: Associations and Mechanisms of Action

A T cell is a type of lymphocyte. T cells are one of the important white blood cells of the immune system, and play a central role in the adaptive immune response. T cells can be easily distinguished from other lymphocytes by the presence of a T-cell receptor TCR on their cell surface. T cells are born from hematopoietic stem cells , [1] found in the bone marrow. Then, developing T cells migrate to the thymus gland to mature.

The Semiotics of Cellular Communication in the Immune System

The fitness gains resulting from development of the adaptive immune system AIS during evolution are still the subject of hot debate. A large random repertoire of antigenic receptors is costly to develop and could be the source of autoimmune reactions. And yet, despite their drawbacks, AIS-like systems seem to have been independently acquired in several phyla of metazoans with very different anatomies, longevities, and lifestyles.

Published on 7. Authors of this article:. Background: The Portable Document Format PDF is the standard file format for the communication of biomedical information via the internet and for electronic scholarly publishing. Although PDF allows for the embedding of three-dimensional 3D objects and although this technology has great potential for the communication of such data, it is not broadly used by the scientific community or by clinicians. Objective: The objective of this review was to provide an overview of existing publications that apply 3D PDF technology and the protocols and tools for the creation of model files and 3D PDFs for scholarly purposes to demonstrate the possibilities and the ways to use this technology.

Gary Gillis says he was drawn to biology because of a strong interest in "how animals work. I want students to know that the organism is not only relevant but central to the field of biology and that the study of organismal structure and function remains a dynamic and exciting area of inquiry. Gillis's research interests focus on how animals use their muscles to generate and coordinate dynamic activities such as locomotion.

Dynamic packaging of DNA into strings of nucleosomes is a major mechanism whereby eukaryotic cells regulate gene expression. As part of this, post-translational modifications of histone proteins are central to the regulation of chromatin structure, playing vital roles in regulating the activation and repression of gene transcription. In the heart, dynamic homeostasis of histone modification — driven by the actions of modifiers and recruitment of downstream effectors — is a fundamental regulator of the transcriptional reprogramming that occurs in the setting of disease-related stress. Here, we examine the growing evidence for histone modification as a key mechanism governing pathological growth and remodeling of the myocardium. Regulation of chromatin in its various active states is controlled significantly through post-translational modifications PTMs of the core histone proteins.

Metrics details. Mental health is increasingly viewed as the presence of various aspects of well-being rather than just the absence of mental illness. The present study examined for the first time the psychometric properties of the Dutch version of the MHC-SF among adolescents, focusing on its factor structure, internal consistency, construct validity, and gender and age factorial invariance. Data were collected from a school-based sample of adolescents Participants completed an online questionnaire in the classroom during regular school hours.

The ability of the outer ocular system to recognize pathogens as foreign and eliminate them is critical to retain corneal transparency, hence preservation of sight. Therefore, a combination of mechanical, anatomical, and immunological defense mechanisms has evolved to protect the outer eye.
