The Multifaceted Roles of B Cells in the Thymus: From Immune Tolerance to Autoimmunity
The thymus is home to a significant number of resident B cells which possess several unique characteristics regarding their origin, phenotype and function.

The Thymus and Central Tolerance [PDF]
T–cell differentiation in the thymus generates a peripheral repertoire of mature T cells that mounts strong responses to foreign antigens but is largely unresponsive to self–antigens. This state of specific immunological tolerance to self–components involves both central and peripheral mechanisms.

Upon recognition of auto-antigens, thymocytes are negatively selected or diverted to a regulatory T cell (Treg) fate. CCR7 is required for negative selection of auto-reactive thymocytes in the thymic medulla.

Is T Cell Negative Selection a Learning Algorithm?
Our immune system can destroy most cells in our body, an ability that needs to be tightly controlled. To prevent autoimmunity, the thymic medulla exposes developing T cells to normal “self” peptides and prevents any responders from entering ...

First Record of \u3ci\u3eAphis Helianthi\u3c/i\u3e (Homoptera: Aphididae) as a Pest of Celery [PDF]
In 1989, the aphid Aphis helianthi severely damaged five of 10 scouted celery fields in west central Michigan. In 1990 and in 1991, A. helianthi again was a problem. reaching pestiferous levels in three of 10 and two of 10 scouted fields.

Redefining thymus medulla specialization for central tolerance. [PDF]
During αβT cell development, the thymus medulla represents an essential microenvironment for T cell tolerance. This functional specialization is attributed to its typical organized topology consisting of a branching structure that contains medullary thymic epithelial cell (mTEC) networks to support negative selection and Foxp3+ T-regulatory cell (T-reg)

Mechanisms of immunological tolerance in central nervous system inflammatory demyelination. [PDF]
Multiple sclerosis is a complex autoimmune disease of the central nervous system that results in a disruption of the balance between pro-inflammatory and anti-inflammatory signals in the immune system.
