1. T cell antigen receptor usage, phenotype and cytokine production in human diseases
Sammanfattning : T lymphocytes are of critical importance for initiating and controlling immune responses, as the T cell receptor (TCR) for antigen allows a highly specific antigen recognition. Determination of TCR usage and characterization of T cell subsets in different diseases helps us understand the underlying immunopathogenic mechanisms, and may also lead to the development of new therapeutic approaches.

2. Studies of T cells in health and disease : receptor usage and cytokine expression
Sammanfattning : T Iymphocytes are crucial components for the initiation and maintenance of an immune response. To identify and characterize different T cells and their antigen specific receptors has important bearing for the understanding of underlying mechanisms in immunopathological processes and also to allow for the design of therapeutic therapies to be used for modulation of immune responses.

3. Regulation of T cell activation and death by the affinity of TCR for peptide/MHC complexes
Sammanfattning : The aim of this study is to investigate the role of the affinity of peptide:MHC/TCR interaction in the regulation of T cell activation, death and repertoire selection. Three aspects pertinent for our understanding of this issue have been analyzed. LÄS MER
4. Natural specific T cell immunity in patients with B-cell chronic lymphocytic leukaemia (B-CLL) : (A clinical and immunological study)
Sammanfattning : Analysis of TCRBV (T-cell receptor B variable) gene usage of the T cell repertoire in patients with B cell chronic lymphocytic leukaemia (B-CLL) and age-matched healthy control donors showed that major perturbations were more frequently seen in the CD4+ T cell subset than in CD8 population. Analysis of the CDR3 length polymorphism revealed a significantly higher degree of clonality within the CD4+ and CD8+ T cell repertoire of patients as compared to the normal control population.

5. T lymphocytes in Wegener’s granulomatosis
Sammanfattning : Wegener's granulomatosis (WG) is a systemic necrotizing vasculitis that affects small and medium size blood vessels. The respiratory tract and lungs are usually compromised with necrotizing granulomatous formations. The aetiology is unknown and untreated the prognosis of generalised WG is very poor. LÄS MER
