Length of the Circulating T Cell Pool Cytomegalovirus Infection

... DNA polymerase, telomeres shorten after each cell division. Therefore, decreasing telomere length can be regarded as a biological clock: when a critical length is reached, telomeres cannot function anymore, and cells will either become senescent or apoptotic (1). Although telomeres steadily decrease ...

... Lymphocytes are called negative detectors because they are trained to bind to nonself; i.e. when a lymphocyte is activated, the IS responds as if nonself were detected. This simple form of learning is known as tolerization, because the lymphocytes are trained to be tolerant of self. Lymphocytes are ...

... Recently described roles for PD-1 expression on DCs and monocytes highlight the possibility that PD-1 signaling may also occur independently of T cell or B cell antigen receptor signaling, possibly by impinging on other receptor signaling pathways (45,46). For example, PD-1 ligation in monocytes has ...

Molecular mimicry

Molecular mimicry is defined as the theoretical possibility that sequence similarities between foreign and self-peptides are sufficient to result in the cross-activation of autoreactive T or B cells by pathogen-derived peptides. Despite the promiscuity of several peptide sequences which can be both foreign and self in nature, a single antibody or TCR (T cell receptor) can be activated by even a few crucial residues which stresses the importance of structural homology in the theory of molecular mimicry. Upon the activation of B or T cells, it is believed that these ""peptide mimic"" specific T or B cells can cross-react with self-epitopes, thus leading to tissue pathology (autoimmunity). Molecular mimicry is a phenomenon that has been just recently discovered as one of several ways in which autoimmunity can be evoked. A molecular mimicking event is, however, more than an epiphenomenon despite its low statistical probability of occurring and these events have serious implications in the onset of many human autoimmune disorders. In the past decade the study of autoimmunity, the failure to recognize self antigens as ""self,"" has grown immensely. Autoimmunity is a result of a loss of immunological tolerance, the ability for an individual to discriminate between self and non-self. Growth in the field of autoimmunity has resulted in more and more frequent diagnosis of autoimmune diseases. Consequently, recent data show that autoimmune diseases affect approximately 1 in 31 people within the general population. Growth has also led to a greater characterization of what autoimmunity is and how it can be studied and treated. With an increased amount of research, there has been tremendous growth in the study of the several different ways in which autoimmunity can occur, one of which is molecular mimicry. The mechanism by which pathogens have evolved, or obtained by chance, similar amino acid sequences or the homologous three-dimensional crystal structure of immunodominant epitopes remains a mystery.
