Autoimmune diseases are the result of improper and uncontrolled immune responses against self-antigens. The NF-kB/Rel family of transcription factors is known to play important roles in the initiation and regulation of immunity against pathogens and foreign antigens. Over time, evidence has accumulated implicating NF-kB as a mediator of autoimmunity and potential therapeutic target for treating autoimmune diseases. In this chapter, we discuss the role of NF-?B in apoptosis and cell proliferation as well as tolerance and autoimmunity.

B7 Family of Costimulatory Molecules in the Induction and Regulation of Autoimmunity
Claudia Jabs, Arlene H. Sharpe and Vijay K. Kuchroo
Normally, most autoreactive T cells are deleted during thymic development. The autoreactive T cells, which escape thymic deletion are kept in check by the mechanisms of peripheral tolerance, which i...

Role of ICOS in T Cell Activation
Jeffrey A. Ledbetter, Erik Espling and Martha Hayden-Ledbetter
Inducible costimulator (ICOS) was recently identified as a novel member of the CD28 family by Hutloff et al.1 A monoclonal antibody (mAb), F44, specific for human ICOS was generated by immunization ...
The ICOS/B7RP-1 Costimulation Pathway
Steven K. Yoshinaga
A novel costimulation pathway homologous to CD28/B7 has recently been discovered and characterized. The Inducible Costimulator (ICOS) is structurally and functionally homologous to CD28. The B7-Rela...
PD-1:PD-1 Ligand Pathway
Gordon J. Freeman and Arlene H. Sharpe
The PD-1:PD-1 ligand pathway is a new pathway within the B7:CD28 superfamily. This pathway consists of the PD-1 receptor and its two ligands PD-L1 (B7-H1) and PD-L2 (B7-DC).1-4 This chapter focuses ...
T Lymphocyte Signaling Pathways Regulated by CD28 and CTLA-4
David J. McKean and Matthew D. Griffin
T lymphocytes in peripheral lymphoid tissues are inactive cells that must receive receptor-initiated signals to become activated and participate in an antigen specific immune response. The integrati...

Jürgen Bajorath
The focal point of this contribution is a critical evaluation of studies designed to explore structure-function relationships of CD28- and B7-like proteins prior to experimental determination of thr...
Negative Costimulatory Functions of B7-H1
Haidong Dong, Hideto Tamura, Sheng-Dian Wang and Lieping Chen
Costimulatory molecules B7-1 and B7-2 belong to an emerging family of the immunoglobulin (Ig) superfamily and share ~25% identical amino acid sequences concentrated in the Ig V- and Ig C-like extracel...
Costimulatory Molecules in T Cell Development, Activation and Effector Function: Similar Activity, Opposite Consequences
Yang Liu, Jian Xin Gao, Xue-Feng Bai, Xingluo Liu, Huiming Zhang and Pan Zheng
Costimulatory molecules were initially dubbed as the second signal determining the fate of naïve T cells after they were engaged by MHC:peptide complex. Accumulating evidence supports the notion that ...
The Role of B7s in Transplantation
Didier A. Mandelbrot, Wayne R. Godfrey, Arlene H. Sharpe and Bruce R. Blazar
The manipulation of the B7 family of molecules holds great promise for developing therapies to be used in clinical transplantation. A major goal in the field of transplan- tation immunology is to...
