Abstract
Natural killer (NK) cells, key effector cells of the innate immune system, play an important role in the clearance and control of Mycobacterium tuberculosis and HIV infections. Here, we utilized peripheral blood specimens from the Improving Retreatment Success CAPRISA 011 study to characterize NK cell phenotypes during active TB in individuals with or without HIV co-infection. We further assessed the effects of TB treatment on NK cell phenotype, and characterized the effects of NK cell phenotypes during active TB on mycobacterial clearance and TB disease severity measured by the presence of lung cavitation. TB/HIV co-infection led to the expansion of functionally impaired CD56neg NK cell subset. TB treatment completion resulted in restoration of total NK cells, NK cell subset redistribution and downregulation of several NK cell activating and inhibitory receptors. Higher percentage of peripheral CD56bright cells was associated with longer time to culture conversion, while higher expression of NKp46 on CD56dim NK cells was associated with lower odds of lung cavitation in the overall cohort and the TB/HIV co-infected participants. Together these results provide a detailed description of peripheral NK cells in TB and TB/HIV co-infection and yield insights into their role in TB disease pathology.

Changes in the NK Cell Repertoire Related to Initiation of TB Treatment and Onset of Immune Reconstitution Inflammatory Syndrome in TB/HIV Co-infected Patients in Rio de Janeiro, Brazil-ANRS 12274. Front Immunol 2019; 10:1800. [PMID: 31456797 PMCID: PMC6700218 DOI: 10.3389/fimmu.2019.01800] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/01/2019] [Accepted: 07/17/2019] [Indexed: 12/30/2022] Open
Abstract
Tuberculosis (TB) is the most common comorbidity and the leading cause of death among HIV-infected individuals. Although the combined antiretroviral therapy (cART) during TB treatment improves the survival of TB/HIV patients, the occurrence of immune reconstitution inflammatory syndrome (IRIS) in some patients poses clinical and scientific challenges. This work aimed to evaluate blood innate lymphocytes during therapeutic intervention for both diseases and their implications for the onset of IRIS. Natural killer (NK) cells, invariant NKT cells (iNKT), γδ T cell subsets, and in vitro NK functional activity were characterized by multiparametric flow cytometry in the following groups: 33 TB/HIV patients (four with paradoxical IRIS), 27 TB and 25 HIV mono-infected subjects (prior to initiation of TB treatment and/or cART and during clinical follow-up to 24 weeks), and 25 healthy controls (HC). Concerning the NK cell repertoire, several activation and inhibitory receptors were skewed in the TB/HIV patients compared to those in the other groups, especially the HCs. Significantly higher expression of CD158a (p = 0.025), NKp80 (p = 0.033), and NKG2C (p = 0.0076) receptors was detected in the TB/HIV IRIS patients than in the non-IRIS patients. Although more NK degranulation was observed in the TB/HIV patients than in the other groups, the therapeutic intervention did not alter the frequency during follow-up (weeks 2-24). A higher frequency of the γδ T cell population was observed in the TB/HIV patients with inversion of the Vδ2+/Vδ2- ratio, especially for those presenting pulmonary TB, suggesting an expansion of particular γδ T subsets during TB/HIV co-infection. In conclusion, HIV infection impacts the frequency of circulating NK cells and γδ T cell subsets in TB/HIV patients. Important modifications of the NK cell repertoire were observed after anti-TB treatment (week 2) but not during the cART/TB follow-up (weeks 6-24). An increase of CD161+ NK cells was related to an unfavorable outcome. Despite the low number of cases, a more preserved NK cell profile was detected in IRIS patients previous to treatment, suggesting a role for these cells in IRIS onset. Longitudinal evaluation of the NK repertoire showed the impact of TB treatment and implicated these cells in TB pathogenesis in TB/HIV co-infected patients.

Abstract
The present study evaluated the frequency and receptor expression pattern of invariant natural killer T (iNKT) cells in human immunodeficiency virus (HIV)-infected individuals. Further, the effect of IL-15 + IL-12 stimulation on iNKT cells was also assessed. The study included 15 individuals each from normal healthy subjects, pulmonary tuberculosis patients, HIV-infected individuals, and patients with HIV and tuberculosis coinfection (HIV-TB). The frequency of iNKT cells and the expression of phenotype, cytotoxic and chemokine receptors were studied by flow cytometry. The number of iNKT cells was significantly depleted in HIV and HIV-TB patients, which upon IL-15 + IL-12 stimulation expanded in HIV. The constitutively expressed natural cytotoxicity receptor, NKp46 was increased in HIV and HIV-TB, which might be the host's response to HIV replication. The distinct expression patterns of chemokine and adhesion receptors suggest that iNKT subsets might traffic to different microenvironment and tissues. High expression of chemokine receptor CCR5 by most iNKT cells suggests that these cells might be more favorable targets of HIV infection. Our results show that IL-15 and IL-12 combination has the ability to expand the selective depletion of iNKT cells in vitro in HIV-infected individuals, but of limited value when coinfected with TB.

The natural killer cell interferon-gamma response to bacteria is diminished in untreated HIV-1 infection and defects persist despite viral suppression. J Acquir Immune Defic Syndr 2014; 65:259-67.

Abstract
OBJECTIVE Natural killer (NK) cells are important in innate immune responses to bacterial and viral pathogens. HIV-1 infection is associated with opportunistic bacterial infections and with microbial translocation, but the nature of the NK cell response to bacteria during HIV-1 infection has not been studied extensively. The objective of this study was to compare NK cell responses to bacteria in HIV-1-infected versus that in uninfected individuals. METHODS Multicolor flow cytometry was used to evaluate the ability of blood NK cell subsets (CD56CD16, CD56CD16, and CD56CD16) from treated, virally suppressed, and untreated viremic subjects with chronic HIV-1 infection and uninfected controls, to secrete interferon gamma (IFN-γ) in response to the in vitro stimulation of peripheral blood mononuclear cells with heat-killed commensal Escherichia coli or pathogenic Salmonella typhimurium. RESULTS All 3 NK cell subsets produced IFN-γ in response to bacteria, but CD56CD16 NK cells were least responsive. Untreated HIV-1-infected donors had increased frequencies of CD56CD16 NK cells and lower overall frequencies of IFN-γ-producing NK cells responding to E. coli and S. typhimurium than did NK cells from uninfected donors. These NK cell defects were not fully restored in antiretroviral therapy-treated donors. Monocytes were necessary for NK cells to respond to bacteria, but the HIV-associated defect was intrinsic to NK cells because the addition of normal monocytes did not restore IFN-γ production in response to bacteria. CONCLUSIONS Functional defects and numeric alterations of NK cell subsets lead to decreased frequencies of bacteria-reactive, IFN-γ-producing NK cells in HIV-1-infected subjects, even those on antiretroviral therapy.

Abstract
BACKGROUND NK cells express several specialized receptors through which they recognize and discriminate virally-infected/tumor cells efficiently from healthy cells and kill them. This ability to lyse is regulated by an array of inhibitory or activating receptors. The present study investigated the frequency of various NK receptors expressed by NK cell subsets from HIV-infected TB patients. The effect of IL-15+IL-12 stimulation on the expression of NK receptors was also studied. METHODOLOGY/PRINCIPAL FINDINGS The study included 15 individuals each from normal healthy subjects, pulmonary tuberculosis patients, HIV-infected individuals and patients with HIV and tuberculosis co-infection. The expression of NK cell receptors was analyzed on two NK cell subsets within the peripheral blood: CD16+CD3- and CD56+CD3- using flow cytometry. The expression of inhibitory receptors (CD158a, CD158b, KIRp70, CD85j and NKG2A) on NK subsets was increased in HIV, when compared to NHS. But the response in HIV-TB was not uniform. Stimulation with IL-15+IL-12 dropped (p<0.05) the expression of CD85j and NKG2A in HIV. The basal expression of natural cytotoxicity receptors (NKp30 and NKp46) on NK cell subsets was lowered (p<0.05) in HIV and HIV-TB as compared to NHS. However, the expression of NKp44 and NKG2D was elevated in HIV. Enhanced NKp46 and NKG2D expression was observed in HIV with IL-15+IL-12 stimulation. The coreceptor NKp80 was found to be expressed in higher numbers on NK subsets from HIV compared to NHS, which elevated with IL-15+IL-12 stimulation. The expression of NK receptors and response to stimulation was primarily on CD56+CD3- subset. CONCLUSIONS/SIGNIFICANCE IL-15+IL-12 has an immunomodulatory effect on NK cell subsets from HIV-infected individuals viz down-regulation of iNKRs, elevation of activatory receptors NKp46 and NKG2D, and induction of coreceptor NKp80. IL-15+IL-12 is not likely to be of value when co-infected with TB probably due to the influence of tuberculosis.

Natural-killer cell-derived cytolytic molecules in HIV-associated pulmonary tuberculosis-role of exogenous interleukins. J Clin Immunol 2010; 30:393-401. [PMID: 20229057 DOI: 10.1007/s10875-010-9380-y] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2009] [Accepted: 02/09/2010] [Indexed: 02/05/2023]
Abstract
OBJECTIVE The ability of NK cells to produce cytolytic molecules is impaired during HIV infection. The objective of the present study is to investigate whether impairment in production of innate cytokines in HIV-infected individuals is responsible for the defective NK cytolytic response. MATERIALS AND METHODS The study included 30 subjects each of normal healthy subjects, pulmonary tuberculosis patients, HIV-infected individuals, and patients with HIV and TB co-infection. Intracellular staining method was adopted to enumerate the NK cells positive for cytolytic molecules. Highest stimulation of cytolytic molecules was seen with IL-15 + IL-12 combination. RESULTS Stimulation with IL-15 + IL-12 showed an increased expression of perforin in NHS and HIV groups. Granzyme A was stimulated only in HIV, even with IL-15 + IL-12. Among the cytolytic molecules, maximal stimulation with IL-15 + IL-12 was seen for Granyme A and Granzyme B. Both the HIV and HIV-TB groups showed an increased response with IL-15 + IL-12 for granulysin. CONCLUSION Supplementing IL-15 + IL-12 in vitro increased the number of NK cells that are expressing cytolytic molecules in HIV-infected individuals but in HIV-TB, the critical cytolytic molecule, perforin is not apparent perhaps due to the influence of TB on HIV.
