Therefore, expert panel, on behalf of the European LeukemiaNet (ELN), AML the identification of the genetic determinants of response to can be grouped into 4 risk groups as shown in Table 1. This has been demonstrated clearly in AML ranges from 66 to 71 years (Surveillance Epidemiology and patients with acute promyelocytic leukemia. Complete remission (CR) can be achieved in vidual AML patient’s disease course, including: (1) at diagnosis 65% to 75% of younger adult patients ( 60 years) and in with regard to classification of the disease and prognostication on approximately 40% to 60% of older patients ( 60 years). The poor achievement of a CR after induction therapy, (2) during PRT and CR rate and overall survival (OS) in older AML patients is follow-up with respect to the choice of the most appropriated attributed to a variety of factors, including inherently poor biology strategy in first CR based on pretreatment markers (ie, intensive (especially a higher incidence of poor-risk karyotypes), comorbidi- ties, and an age-related functional decline.

This partly reflects the technical difficulties mentioned above discount quibron-t 400mg line allergy ultratab, but may also occur because the CTL response is variable 400 mg quibron-t free shipping allergy testing codes. The timing and methods of measurement may influence five aspects of theobserved CTL response (Gianfrani et al. First, some studies measure primary CTL response, whereas other studies measure memory CTLs stimulated by secondary challenge. Second, persistent viral infections may evolvewithinahost, causing the host to develop a sequence of focused CTL responses. Third, some methods measure relatively rare CTL-epitope combina- tions better than other methods. Relatively insensitive measurement 80 CHAPTER 6 leads to observations of narrow response. Relatively sensitive methods may pick up relatively weak CTL responses. The existence of a response does not mean that the response was a significant fraction of the total CTL expansion. Fourth, it is often necessary to choose a priori a relatively small panel of epitopes as probes for the presence of matching CTLs. As the meth- ods improve to predict CTL epitopes, the number of epitopes observed to stimulate CTL response will rise. Fifth, some studies measure CTL response aggregated over several hosts. Each host may have a relatively narrow response, but hosts may differ in their choice of epitopes. With these issues in mind, we can make some sense of the contrast- ing reports on the diversity CTL response. On the one hand, studies of influenza (Bednarek et al. These studies emphasize the dominance of certain CTL clones at a particular time during infection within a single host (Murali-Krishna et al. On the other hand, observed human CTLresponses were broad and multispecific against hepatitisBand C viruses and against HIV (Chisari 1995; McMichael and Phillips 1997; Rehermann et al. These pathogens tend to be ge- netically heterogeneous within a single host and may evolve by escape mutants in dominant epitopes. Thus, CTL focus may change over the course of infection within a single host. However, their measurements were aggregated over several hosts. Eachhosttended to respond strong- ly to a dominant epitope associated with one of its class I MHC alleles and to have memory CTLs for a small number of other epitopes for that dominant class I allele and for another class I allele. It seems that a few CTL clones prevail numerically within each host, but other clones may be stimulated and hosts may vary in which clones react to a particular epitope. TIME OF CTL RECRUITMENT Three factors influence the relative abundance of expanded T cell clones: frequency in the naive repertoire, rate of cell division, and time IMMUNODOMINANCE WITHIN HOSTS 81 of initialexpansion. Those dominant clones were not particularly frequent in the naive repertoire. The relative abundances did not change between dominant and subdominant CTL clones that in- creased in abundance from the early to late stages of the T cell response, suggesting that expanding clones didnotvaryintheirrate of cellular division. The dominant CTL clones began their numerical expansion earlier than subordinate clones. CTL clones double every six to eight hours; thus a one-day advance in clonal activation causes an 8- to 16-fold dif- ference in cellular abundance. The timing of initial clonal expansion ap- pears to control immunodominance in this case. INITIAL STIMULATION BY ENDOGENOUS VERSUS EXOGENOUS ANTIGEN Naive CD8+ Tcells must be activated to proliferate and to become armed with killer function as CTLs. Naive CD8+ cells are also confined to the blood and lymph systems and generally do not pass outside to most tissues, whereas the armed CTLs can exit to infected tissues. The confinement of naive CD8+ cells raises a paradox (Reimann and Schirmbeck 1999). To be activated, the CD8+ cells must bind peptide- MHC class I complexes on the surface of cells with foreign antigen. But if the infection is not intheblood or lymph compartments, the naive Tcells cannot reach the site of infection. Somehow, the naive CD8+ cells must encounter peptide-MHC class I complexes within the blood or lymph compartments even though the site of infection may be outside those compartments. One possible solution depends on the distinction between endoge- nous and exogenous antigen (Schumacher 1999; Sigal et al. The CD8+ Tcellistraditionally thought to bind primarily to pathogen anti- gens created endogenously within infected host cells. Those antigens aredigested within the cell and transported to the endoplasmic retic- ulum, where they bind MHC class I molecules.
