Abstract
In human cutaneous leishmaniasis (CL), the immune response is mainly mediated by
T-cells. The role of CD8+ T-lymphocytes, which are related to healing or
deleterious functions, in affecting clinical outcome is controversial. The aim of
this study was to evaluate T-cell receptor diversity in late-differentiated effector
(LDE) and memory CD8+ T-cell subsets in order to create a profile of
specific clones engaged in deleterious or protective CL immune responses. Healthy
subjects, patients with active disease (PAD) and clinically cured patients were
enrolled in the study. Total CD8+ T-lymphocytes showed a disturbance in
the expression of the Vβ2, Vβ9, Vβ13.2, Vβ18 and Vβ23 families. The analyses of
CD8+T-lymphocyte subsets showed high frequencies of LDE
CD8+T-lymphocytes expressing Vβ12 and Vβ22 in PAD, as well as
effector-memory CD8+ T-cells expressing Vβ22. We also observed low
frequencies of effector and central-memory CD8+ T-cells expressing Vβ2 in
PAD, which correlated with a greater lesion size. Particular Vβ expansions point to
CD8+ T-cell clones that are selected during CL immune responses,
suggesting that CD8+ T-lymphocytes expressing Vβ12 or Vβ22 are involved in
a LDE response and that Vβ2 contractions in memory CD8+T-cells are
associated with larger lesions.

Abstract
In this study, we used proteomics and biological network analysis to evaluate the potential biological processes and components present in the identified proteins of biopsies from cutaneous leishmaniasis (CL) patients infected by Leishmania braziliensis in comparison with normal skin. We identified 59 proteins differently expressed in samples from infected and normal skin. Biological network analysis employing identified proteins showed the presence of networks that may be involved in the cell death mediated by cytotoxic T lymphocytes. After immunohistochemical analyses, the expression of caspase-9, caspase-3, and granzyme B was validated in the tissue and positively correlated with the lesion size in CL patients. In conclusion, this work identified differentially expressed proteins in the inflammatory site of CL, revealed enhanced expression of caspase-9, and highlighted mechanisms associated with the progression of tissue damage observed in lesions.

The skin homing receptor cutaneous leucocyte-associated antigen (CLA) is up-regulated by Leishmania antigens in T lymphocytes during active cutaneous leishmaniasis. Clin Exp Immunol 2009; 157:377-84.

Abstract
The cutaneous leucocyte-associated antigen receptor (CLA) can direct Leishmania-specific T lymphocytes towards inflamed skin lesions. Homing receptors [CLA, lymphocyte-associated antigen 1 (LFA-1) or CD62L] were analysed in lymphocytes from blood and cutaneous leishmaniasis (CL) lesions. CL patients with active lesions (A-CL) presented lower levels of T lymphocytes expressing the CLA(+) phenotype (T CD4(+) = 10.4% +/- 7.5% and T CD8(+) = 5.8% +/- 3.4%) than did healthy subjects (HS) (T CD4(+) = 19.3% +/- 13.1% and T CD8(+) = 21.6% +/- 8.8%), notably in T CD8(+) (P < 0.001). In clinically cured patients these percentages returned to levels observed in HS. Leishmanial antigens up-regulated CLA in T cells (CLA(+) in T CD4(+) = 33.3% +/- 14.1%; CLA(+) in T CD8(+) = 22.4% +/- 9.4%) from A-CL but not from HS. An enrichment of CLA(+) cells was observed in lesions (CLA(+) in T CD4(+) = 45.9% +/- 22.5%; CLA(+) in T CD8(+) = 46.4% +/- 16.1%) in comparison with blood (CLA(+) in T CD4(+) = 10.4% +/- 7.5%; CLA(+) in T CD8(+) = 5.8% +/- 3.4%). Conversely, LFA-1 was highly expressed in CD8(+) T cells and augmented in CD4(+) T from peripheral blood of A-CL patients. In contrast, CD62L was not affected. These results suggest that Leishmania antigens can modulate molecules responsible for migration to skin lesions, potentially influencing the cell composition of inflammatory infiltrate of leishmaniasis or even the severity of the disease.
