NK cytotoxicity against CD4+ T cells during HIV-1 infection: a gp41 peptide induces the expression of an NKp44 ligand.
|

|
Here we show that a cellular ligand for NKp44 (NKp44L) is expressed during HIV-1 infection and is correlated with both the progression of CD4+ T cell depletion and the increase of viral load.

|
CD4+ T cells expressing this ligand are highly sensitive to the NK lysis activity mediated by NKp44+ NK cells.

Bovine natural killer (NK) cells were recently identified by positive selection of a NK cell-activating receptor p46 (NKp46)+ CD3- lymphocyte population, which expresses CD25 and CD8 and lyses tumor cell lines following stimulation with recombinant interleukin-2.

In the current work, we characterize the cytotoxic/effector potential of a CD3(-)CD8(-)CD11b- population isolated through negative selection of bovine peripheral blood leukocytes.
|

|
This population is CD25(lo)CD62(hi) when isolated and becomes CD25hiCD62L(lo) following cytokine stimulation.

Activated bovine NK cells increase expression of granulysin, interferon-gamma, and perforin and have cytotoxic activity against human tumor cells and Mycobacterium bovis bacillus Calmette-Guerin-infected alveolar and monocyte-derived macrophages.

Expression of a bovine homologue of the CD56 neural adhesion molecule expressed by human NK cells was detected in mRNA from brain tissue but was not detected in peripheral blood mononuclear cells or purified NK cell mRNA.
|

|
Analysis of mRNA from nonstimulated peripheral blood NK cells demonstrates the constitutive expression of homologues of human NK receptors NKp46, CD244, and CD94 and the granule proteins granulysin and perforin.

Phorbol ester-stimulated CD8+ T cells also expressed CD244 and CD94, and CD4+ T cells expressed CD94.

We decided to assess the levels of NK and NKT lymphocytes and the expression levels of different membrane receptors (NKp44, NKp46, NKG2A, killer cell immune-like receptor [KIR] 3DL1/DS1, KIR2DL1/DS1, and CD161) in peripheral blood samples of patients with influenza (n = 17) and healthy individuals immunized against this virus (seasonal and [H1N1]pdm2009 influenza vaccines; n = 15 and 12, respectively).
|
18 |
23784853
|
We found that the patients with severe influenza (n = 9) showed significant increases in the percentages of NKp46(+) NKp44(+) NK cells and the proportions of NK and NKT lymphocytes expressing KIR2DL1 and KIR3DL1 and reductions in the percentages of NKp46(+) NKp44(-) NK cells compared to those in the healthy controls (n = 27).

Natural killer cell cytokine response to M. bovis BCG Is associated with inhibited proliferation, increased apoptosis and ultimate depletion of NKp44(+)CD56(bright) cells.
|
20 |
23874793
|
We found that M. bovis BCG mediates apoptosis of NK cells only in the context of IL-2 stimulation during which CD56(bright) NK cells are releasing IFN-γ in response to mycobacteria.
|
21 |
23874793
|
We found that the presence of mycobacteria prevented the IL-2 induced proliferation and surface expression of NKp44 receptor by the CD56(bright) population.

Our data suggests that stimulation with VACV triggers a cytotoxic response by NK cells marked by an increase of NCRs: NKp30, NKp44, and NKp46 in infected (vaccinated and unvaccinated) subjects and in non-infected vaccinated patients, when compared with non-infected unvaccinated individuals.
|

|
We demonstrated that stimulation with VACV downregulates the percentage of expression of Perforin, Granzyme A, and CD107a, but upregulate CD94 in infected (vaccinated and unvaccinated) subjects and in non-infected vaccinated patients, when compared with non-infected unvaccinated individuals.

Our data suggest that the expression of NCRs NKp30, NKp44, NKp46 and cytokines by NK cells are important in the innate response against VACV.

In the absence of significant changes in other NK cell markers (CD45RO, NKp44, CXCR6, CD57, NKG2C, CCR7, CD62L and CD27), influenza vaccines induced memory NK cells with the distinct feature of intracellular NKp46 expression.
