Vertebral osteomyelitis due to in a diabetic patient. A case report and literature review.

Staphylococci are the most frequent cause of vertebral osteomyelitis, but infections due to unusual pathogens are also reported. We describe a rare case of spondylodiscitis due to . A 74-year-old diabetic male was evaluated for fever and back pain.

Nonantigen specific CD8+ T suppressor lymphocytes originate from CD8+CD28- T cells and inhibit both T-cell proliferation and CTL function.

Nonantigen specific CD8+ suppressor T lymphocytes (CD8+ Ts) inhibit T-cell proliferation of antigen-specific T lymphocytes. The impossibility to generate in vitro these cells has been correlated with the appearance of relapses in patients affected by autoimmune diseases, suggesting the involvement of these cells in immune regulation. This study was aimed to identify circulating precursors and to characterize the phenotype and mechanism of action of CD8+ Ts.

Migration of V delta 1 and V delta 2 T cells in response to CXCR3 and CXCR4 ligands in healthy donors and HIV-1-infected patients: competition by HIV-1 Tat.

We show that HIV-1-infected patients have increased concentrations of circulating V delta 1 T cells (2.2%-9.0% of T lymphocytes; healthy donors, 1.
