Consequences of antigen self-presentation by tumor-specific cytotoxic T cells.

2000

Abstract CDS-positive cytotoxic T cells (CTL) recognize antigenic peptides in combination with major histocompatibility complex (MHC) class I molecules on the surface of syngeneic antigen presenting cells (APC). In the present paper we show that cells from tumor antigen-specific CTL clones present their cognate antigenic peptide to other CTL from the same clone. Inter-CTL peptide presentation resulted in activation of the cells of one CTL clone to MHC-unrestricted lysis of bystander cells. In contrast to the behaviour of this clone, another CTL clone did not lyse bystander cells after incubation with the cognate peptide, but was activated to self-destruction. The human herpes virus Epstein-…

N-Terminal amino acid sequence analysis indicates that isolated atrial amyloid is derived from atrial natriuretic peptide

1988

Isolated atrial amyloid, the most frequent senile cardiac amyloid type, was chemically analysed. Amyloid fibrils obtained from a patient (NIP) were extracted and the predominant low-molecular-weight polypeptide (approximately 3.5 kDa, designated ASc2 NIP) was isolated by size exclusion high performance liquid chromatography in 60% formic acid. N-Terminal amino acid sequence analysis of this polypeptide was identical to that of the atrial natriuretic peptide alpha-hANP for the first 12 residues determined.

The nucleotide and partial amino acid sequences of rat fetuin. Identity with the natural tyrosine kinase inhibitor of the rat insulin receptor.

1992

Fetuins are among the major plasma proteins, yet their biological role has remained elusive. Here we report the molecular cloning of rat fetuin and the sequence analysis of a full-length clone, RF619 of 1456 bp with an open reading frame of 1056 bp encoding 352 amino acid residues. The coding part of RF619 was identical with the cDNA sequence of the natural inhibitor of the insulin receptor tyrosine kinase from rat (pp63) except for four substitutions and a single base insertion causing divergence of the predicted protein sequences. Partial amino acid sequences of rat plasma fetuin were in agreement with the predictions based on the RF619 cDNA. Purified rat fetuin inhibited the insulin rece…
