Androgens Accelerate Thymocyte Apoptosis

Nitric Oxide Induces Thymocyte Apoptosis

Plasma membrane potential in thymocyte apoptosis.

Apoptosis is accompanied by major changes in ion compartmentalization and transmembrane potentials. Thymocyte apoptosis is characterized by an early dissipation of the mitochondrial transmembrane potential, with transient mitochondrial swelling and a subsequent loss of plasma membrane potential (DeltaP sip) related to the loss of cytosolic K+, cellular shrinkage, and DNA fragmentation. Thus, a ...

Thymocyte Apoptosis Induced by T Cell

C5a receptor and thymocyte apoptosis in sepsis.

In sepsis, apoptosis occurs in many different organs. The mediators responsible for induction of apoptosis are not clearly known, although there are some suggestions that C5a and the C5a receptor (C5aR) might be directly linked to apoptosis. In the cecal ligation/puncture (CLP) model of sepsis in rats, apoptosis occurs early in a variety of organs, especially in the thymus. We demonstrate that ...

Plasmodium berghei ANKA infection induces thymocyte apoptosis and thymocyte depletion in CBA mice.

Immune responses to malaria infections are characterized by strong T and B cell activation, which, in addition of potentially causing immunopathology, are of poor efficacy against the infection. It is possible that the thymus is involved in the origin of immunopathological reactions and a target during malaria infections. This work was developed in an attempt to further clarify these points. We...
