Evaluation of CEA, TPA, Ca 15.3, Ca 549 and TPS in the monitoring of metastatic breast cancer
No full textEvaluation of CEA, TPA, CA 15-3, CA 549 and TPS in the monitoring of metastatic breast cancer
No full textMonitoring the response to treatment in relapsed breast cancer patients is one of the chief uses of tumor markers. Thus far the carcinoembryonic antigen (CEA)-tissue polypeptide antigen (TPA)-breast cancer associated antigen 115 D8/DF3 (CA 15-3) association has been routinely used to follow-up breast cancer patients. We have found that TPA reflects the response to treatment much better than CEA and slightly better than CA 15-3. Recently carcinoma associated antigen 549 (CA 549) and tissue polypeptide specific antigen (TPS) have been reported to be highly sensitive tumor markers for breast cancer. TPS is claimed to be particularly suitable for monitoring the response to treatment because of its more specific assessment of proliferation activity. Therefore, in 13 relapsed patients with prolonged follow-up and detailed clinical-instrumental information, the mean percentage of samples with high CEA, TPA, and CA 15-3 values and their expressions were compared with those of CA 549 and TPS. All markers were also evaluated in terms of their correspondence with the evolution of disease. The correspondence with clinical-instrumental behaviour was scored absent (0), poor (1), good (2) and very good (3) by three different observers. Other more suitable associations than those already used were also investigated. It was found that CA 15-3 and CA 549 were expressed more often (92%) than TPS (85%), TPA (60%) and CEA (46%).(ABSTRACT TRUNCATED AT 250 WORDS
The presence of antibodies against HIV peptides in the sera of alloimmune mice and thalassemic patients is due to a polyclonal activation mechanism
No full textThis paper analyzes the HIV-1 gp120 epitope specificity and activation mechanisms (i.e., polyclonal versus oligoclonal) of antibodies present in the sera of alloimmune mice and humans. Sera from CBA mice engrafted with C57BL/6 lymphoid cells significantly reacted against the gp120-derived peptide aa 261-270, which shares high homology with the membrane-proximal domain of HLA class II beta-chains (HLA/gp120) and against the HIV gp120 V3 loop-derived peptides DP32 (HIV-1 MN-derived aa 302-334) and C53 (HIV-1 IIIB-derived aa 304-318). The same sera also reacted against the HIV-unrelated peptide necdin. Moreover, sera from BALB/c mice injected with LPS presented antibodies reacting against both HIV-related and -unrelated peptides, suggesting that similar mechanisms are shared in alloimmune and LPS-treated mice. A similar analysis was then performed on the sera of patients affected with beta-thalassemia major, receiving at least 10 blood transfusions/year. In particular, 15 of 58 (26%) sera from HIV-uninfected thalassemic patients showed a significantly reactivity against the HLA/gp120-derived peptides. Moreover, 22 of 58 (38%) sera from the same cohort showed a significant reactivity against DP32 peptide. This reactivity was related to a polyclonal activation mechanism since the DP32-reactive sera significantly bound a panel of HIV-unrelated peptides, as observed by testing 22 sera against necdin, 21 against HSP65 kDa, 21 against amyloid-1, and 17 against MAGE-1 peptides. Moreover, a significant increase of IgG concentration was also observed in all thalassemic sera, when compared to healthy controls, without regard to the anti-gp120 antibody reactivity. Taken together, these results indicate that (i) allogeneic stimuli may induce anti-gp120 antibodies in CBA and in 38% of polytransfused patients and (ii) this reactivity is related to a polyclonal activation mechanism but not to a heightened concentration of IgG.

No full textKey role of human leukocyte antigen in modulating HIV progression: an overview of the possible applications.
No full textHuman immunodeficiency virus (HIV) disease progression depends on several host factors. Among them human leukocyte antigen (HLA) locus has a main role due to the peculiar capability to modulate both innate and adaptive immune response. In this review, the role of HLA molecules and its receptors in HIV progression toward acquired immunodeficiency disease syndrome is summarized. A better knowledge about HLA-peptide presentation and recognition by immune cells will open new applications in HIV vaccine and diagnostics design
