Infección Activa por el Citomegalovirus (CMV) en el trasplante alogénico de precursores hematopoyéticos:Investigación de nuevos factores biológicos p…

2016

Citomegalovirus (CMV) es causa frecuente de morbididad y mortalidad en el marco del trasplante alogénico de precursores hematopoyéticos (alo-TPH). CMV puede ocasionar enfermedad orgánica o tisular (neumonía intersticial o enfermedad gastrointestinal, con mayor frecuencia), en virtud de su “citopatogenicidad” . CMV también puede causar morbididad a través de mecanismos indirectos, relacionados con su capacidad inmunosupresora y pro-inflamatoria; en ese contexto, CMV parece incrementar el riesgo de “superinfección” bacteriana y fúngica y de la enfermedad injerto contra huésped (EICH). La reactivación de la infección crónica persistente por el CMV es un suceso frecuente en el paciente alo-TPH.…

GH-suppression test in acromegaly: comparison between OGTT and chocolate test

Treatment results of acromegaly as analyzed by different criteria.

1997

Results of treatment of acromegaly are often incomparable due to the different criteria which have been used for defining cure or control of disease. At the present time it is widely accepted, that the main criteria of cure must be normalization of IGF-1 and a GH in the OGTT2 ng/ml. In this retrospective study we investigated the endocrinological results of 56 patients, who were surgically treated because of a GH-producing pituitary adenoma, by different criteria. Twelve of our patients had had additional medical treatment after surgery, two received radiotherapy. At a mean follow-up of 34 months after surgery 66% of patients had a basal GH5 ng/ml, 64% had a GH in the OGTT2 ng/ml and 73% ha…

Cytomegalovirus Misleads Its Host by Priming of CD8 T Cells Specific for an Epitope Not Presented in Infected Tissues

2003

Cytomegaloviruses (CMVs) code for several proteins that inhibit the presentation of antigenic peptides to CD8 T cells. Although the molecular mechanisms of CMV interference with the major histocompatibility complex class I pathway are long understood, surprisingly little evidence exists to support a role in vivo. Here we document the first example of the presentation of an antigenic peptide being blocked by a CMV immune evasion protein in organs relevant to CMV disease. Although this Db-restricted peptide, which is derived from the antiapoptotic protein M45 of murine CMV (mCMV), is classified as an immunodominant peptide based on response magnitude and long-term memory, adoptive transfer of…

Subdominant CD8 T-Cell Epitopes Account for Protection against Cytomegalovirus Independent of Immunodomination▿ †

2008

ABSTRACTCytomegalovirus (CMV) infection continues to be a complication in recipients of hematopoietic stem cell transplantation (HSCT). Preexisting donor immunity is recognized as a favorable prognostic factor for the reconstitution of protective antiviral immunity mediated primarily by CD8 T cells. Furthermore, adoptive transfer of CMV-specific memory CD8 T (CD8-TM) cells is a therapeutic option for preventing CMV disease in HSCT recipients. Given the different CMV infection histories of donor and recipient, a problem may arise from an antigenic mismatch between the CMV variant that has primed donor immunity and the CMV variant acquired by the recipient. Here, we have used the BALB/c mouse…

Highly protective in vivo function of cytomegalovirus IE1 epitope-specific memory CD8 T cells purified by T-cell receptor-based cell sorting.

ABSTRACTReconstitution of antiviral CD8 T cells is essential for controlling cytomegalovirus (CMV) infection after bone marrow transplantation. Accordingly, polyclonal CD8 T cells derived from BALB/c mice infected with murine CMV protect immunocompromised adoptive transfer recipients against CMV disease. The protective population comprises CD8 T cells with T-cell receptors (TCRs) specific for defined and for as-yet-unknown viral epitopes, as well as a majority of nonprotective cells with unrelated specificities. Defined epitopes include IE1/m123 and m164, which are immunodominant in terms of the magnitude of the CD8 T-cell response, and a panel of subordinate epitopes (m04, m18, M45, M83, a…
