Secreted S100A4 causes asthmatic airway epithelial barrier dysfunction induced by house dust mite extracts via activating VEGFA/VEGFR2 pathway. ENVIRONMENTAL TOXICOLOGY 2023; 38:1431-1444.

Abstract
The airway epithelial barrier dysfunction plays a crucial role in pathogenesis of asthma and causes the amplification of downstream inflammatory signal pathway. S100 calcium binding protein A4 (S100A4), which promotes metastasis, have recently been discovered as an effective inflammatory factor and elevated in bronchoalveolar lavage fluid in asthmatic mice. Vascular endothelial growth factor-A (VEGFA), is considered as vital regulator in vascular physiological activities. Here, we explored the probably function of S100A4 and VEGFA in asthma model dealt with house dust mite (HDM) extracts. Our results showed that secreted S100A4 caused epithelial barrier dysfunction, airway inflammation and the release of T-helper 2 cytokines through the activation of VEGFA/VEGFR2 signaling pathway, which could be partial reversed by S100A4 polyclonal antibody, niclosamide and S100A4 knockdown, representing a potential therapeutic target for airway epithelial barrier dysfunction in asthma.

Obesity alters the mouse endometrial transcriptome in a cell context-dependent manner. Reprod Biol Endocrinol 2022; 20:163. [PMID: 36424602 PMCID: PMC9686036 DOI: 10.1186/s12958-022-01030-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/05/2022] [Accepted: 11/02/2022] [Indexed: 11/25/2022] Open
Abstract
Obesity impacts fertility and is positively correlated with endometrial hyperplasia and endometrial cancer occurrence. Endometrial epithelia often harbor disease driver-mutations, while endometrial stroma are highly regulative of neighboring epithelia. Here, we sought to determine distinct transcriptome changes occurring in individual cell types in the obese mouse uterus. Outbred CD-1 mice were fed high-fat or control diets for 18 weeks, estrous cycle staged, and endometrial epithelia, macrophages, and stroma isolated for transcriptomic analysis. High-fat diet mice displayed increased body mass and developed glucose intolerance, hyperinsulinemia, and fatty liver. Obese mouse epithelia displayed differential gene expression for genes related to innate immunity and leukocyte chemotaxis. The obese mouse stroma differentially expressed factors related to circadian rhythm, and expression of these genes correlated with glucose tolerance or body mass. We observed correlations between F4/80 + macrophage numbers, Cleaved Caspase 3 (CC3) apoptosis marker staining and glucose intolerance among obese mice, including a subgroup of obese mice with high CC3 + luminal epithelia. This subgroup displayed differential gene expression among all cell types, with pathways related to immune escape in epithelia and macrophages, while the stroma dysregulated pathways related to regulation of epithelia. These results suggest an important role for differential response of both the epithelia and stroma in their response to obesity, while macrophages are dysregulated in the context of apoptotic epithelia. The obesity-related gene expression programs in cells within the uterine microenvironment may influence the ability of the endometrium to function during pregnancy and influence disease pathogenesis.

Abstract
Emergence of mutant SARS-CoV-2 strains associated with an increased risk of COVID-19-related death necessitates better understanding of the early viral dynamics, host responses and immunopathology. Single cell RNAseq (scRNAseq) allows for the study of individual cells, uncovering heterogeneous and variable responses to environment, infection and inflammation. While studies have reported immune profiling using scRNAseq in terminal human COVID-19 patients, performing longitudinal immune cell dynamics in humans is challenging. Macaques are a suitable model of SARS-CoV-2 infection. Our longitudinal scRNAseq of bronchoalveolar lavage (BAL) cell suspensions from young rhesus macaques infected with SARS-CoV-2 (n = 6) demonstrates dynamic changes in transcriptional landscape 3 days post- SARS-CoV-2-infection (3dpi; peak viremia), relative to 14-17dpi (recovery phase) and pre-infection (baseline) showing accumulation of distinct populations of both macrophages and T-lymphocytes expressing strong interferon-driven inflammatory gene signature at 3dpi. Type I interferon response is induced in the plasmacytoid dendritic cells with appearance of a distinct HLADR+CD68+CD163+SIGLEC1+ macrophage population exhibiting higher angiotensin-converting enzyme 2 (ACE2) expression. These macrophages are significantly enriched in the lungs of macaques at 3dpi and harbor SARS-CoV-2 while expressing a strong interferon-driven innate anti-viral gene signature. The accumulation of these responses correlated with decline in viremia and recovery.

Abstract
One of the basic features of immune system is the ability to sustain balance between activation and suppression of effector lymphocytes. In this process a key role belongs to the subpopulation of cells called regulatory T cells (Treg). Many cancer and autoimmune diseases are caused by malfunctions of Treg, and investigation of this subpopulation is important for development of new therapeutic approaches. In this study, we demonstrate that regulatory T cells can migrate along the concentration gradient of Tag7-Mts1 complex, and also they produce agents that induce blood cells migration.

Abstract
ABSTRACT Peptidoglycan recognition protein 1 (PGLYRP1) has long been believed to play an important role in infectious and immune diseases. We hypothesized that it might be involved in the pathophysiology of atherosclerotic diseases, which are regarded as chronic inflammatory diseases. Serum PGLYRP1 concentrations were measured in 240 patients with coronary artery disease (CAD) and 209 age-matched and gender-matched individuals with normal coronary arteries using enzyme-linked immunosorbent assay. The expression of PGLYRP1 in atherosclerotic plaques was quantified using western blotting and immunostaining. ApoE-/- mice, fed a high-fat diet, were randomly given intraperitoneal injections of saline or recombinant PGLYRP1 protein for 12 weeks. The effects of PGLYRP1 on human umbilical vein endothelial cells were investigated by western blotting. Higher concentrations of PGLYRP1 were significantly associated with a higher risk of CAD. The odd ratio for upper quartile versus lower quartile was 2.24 (95% confidence interval: 1.21-4.13) after adjustment for sex, age, smoking, body mass index, lipid profile, blood pressure, fasting glucose, and estimated glomerular filtration rate. PGLYRP1 was highly expressed in murine atherosclerotic plaques. Recombinant PGLYRP1 protein alleviated the progress of atherosclerosis in vivo and reduced the expression of endothelial cells' adhesion molecules in vitro. In conclusion, our study suggested that PGLYRP1 is upregulated in patients with CAD and atherosclerotic plaques. PGLYRP1 may participate in the pathophysiological process of atherosclerosis.

Abstract
Search for novel regulatory protein fragments with potential functional roles is required both for understanding the immune response mechanisms and the development of targeted immunotherapy. Earlier we demonstrated that the PGLYRP1/Tag7 innate immunity protein can be regarded as an inhibitor of TNFα cytotoxic activity via the interaction with its TNF receptor 1 (TNFR1). A C-terminal peptide fragment 17.1 of the molecule is responsible for this function. In this study we have identified a minimal 8-mer region of this peptide (hereinafter – 17.1A) capable to bind to TNFR1. As a result of such interaction, the cytotoxic signals induced by this receptor are blocked. Also, this peptide demonstrates an anti-inflammatory activity in vivo in the complete Freund’s adjuvant (CFA)-induced arthritis model in laboratory mice. Peptide 17.1A is capable to reduce periarticular inflammation, inhibit the development of synovitis and exhibit a protective effect on cartilage and bone tissues. This peptide can turn out to be a promising medicinal agent for autoimmune arthritis and other diseases.

Abstract
One of the promising fields of modern molecular biology is the search for new proteins that regulate the various stages of the immune response and the investigation of the molecular mechanisms of action of these proteins. Such proteins include the multifunctional protein PGLYRP1/Tag7, belonging to the PGRP-S protein family, whose gene was discovered in mice at the Institute of Gene Biology, Russian Academy of Sciences, in 1996. PGLYRP1/Tag7 is classified as a protein of innate immunity; however, it can also participate in the regulation of acquired immunity mechanisms. In this paper, we consider the involvement of PGLYRP1/Tag7 in the triggering of antimicrobial defense mechanisms and formation of subsets of cytotoxic lymphocytes that kill tumor cells. The paper emphasizes that the multifaceted functional activity of Tag7 in the immune response has to do with its ability to interact with various proteins to form stable protein complexes. Hsp70-associated Tag7 can induce the death of tumor cells carrying the TNFR1 receptor. Tag7, associated with the Mts1 (S100A4) protein, can stimulate the migration of innate and adaptive immune cytotoxic lymphocytes to a lesion site. Involvement of Tag7 in the regulation of immunological processes suggests that it may be considered as a promising agent in cancer therapy. These properties of Tag7 were used to develop autologous vaccines that have passed the first and second phases of clinical trials in patients with end-stage melanoma and renal cancer. The C-terminal peptide of Tag7, isolated by limited proteolysis, was shown to protect the cartilage and bone tissue of the ankle joint in mice with induced autoimmune arthritis and may be a promising drug for suppressing the development of inflammatory processes.

Abstract
Investigation of interactions between a pro-inflammatory cytokine tumor necrosis factor (TNFα) and its receptor is required for the development of new treatments for autoimmune diseases associated with the adverse effects of TNFα. Earlier, we demonstrated that the innate immunity protein Tag7 (PGRP-S, PGLYRP1) can interact with the TNFα receptor, TNFR1, and block the transduction of apoptotic signals through this receptor. A complex formed between the Tag7 protein and the major heat shock protein Hsp70 can activate TNFR1 receptor and induce tumor cell death via either apoptotic or necroptotic pathway. In this study, we show that a 12-mer peptide, designated 17.1, which was derived from the Tag7 protein, can be regarded as a novel TNFα inhibitor, also is able to form a cytotoxic complex with the heat shock protein Hsp70. This finding demonstrates a new role for Hsp70 protein in the immune response. Also, this new inhibitory 17.1 peptide demonstrates an anti-inflammatory activity in the complete Freund's adjuvant (CFA)-induced autoimmune arthritis model in laboratory mice. It appears that the 17.1 peptide could potentially be used as an anti-inflammatory agent.

Abstract
Hepatocellular carcinoma (HCC) is the most commonly diagnosed liver cancer, accounting for ~90% of all primary malignancy of the liver. Although various medical treatments have been used as systemic therapies, patient survival time may be extended by only a few months. Moreover, the underlying mechanisms of HCC development and progression remain poorly understood. In the present study, the single-cell transcriptome of one in vivo HCC tumor sample, two in vitro HCC cell lines and normal peripheral blood mononuclear cells were analysed in order to identify the potential mechanism underlying the development and progression of HCC. Interestingly, JunB proto-oncogene was identified to serve a role in the immune response and in development and progression of HCC, potentially contributing to the development of novel therapeutics for HCC patients.

Peptidoglycan Recognition Protein 4 Limits Bacterial Clearance and Inflammation in Lungs by Control of the Gut Microbiota. Front Immunol 2019; 10:2106. [PMID: 31616404 PMCID: PMC6763742 DOI: 10.3389/fimmu.2019.02106] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2019] [Accepted: 08/21/2019] [Indexed: 12/19/2022] Open
Abstract
Streptococcus pneumoniae is the most frequent cause of community-acquired pneumonia. Endogenous host defense molecules such as peptidoglycan recognition protein 4 (PGLYRP4) might influence the course of this disease. To the best of our knowledge, there are no reports on the relevance of PGLYRP4 in pneumonia. Therefore, wild type (WT) and PGLYRP4-deficient (PGLYRP4KO) mice were analyzed in an in vivo and in vitro experimental setting to examine the influence of PGLYRP4 on the course of pneumococcal pneumonia. Furthermore, caecal 16S rRNA microbiome analysis was performed, and microbiota were transferred to germfree WT mice to assess the influence of microbiotal communities on the bacterial burden. Mice lacking PGLYRP4 displayed an enhanced bacterial clearance in the lungs, and fewer mice developed bacteremia. In addition, an increased recruitment of immune cells to the site of infection, and an enhanced bacterial killing by stronger activation of phagocytes could be shown. This may depend partly on the detected higher expression of complement factors, interferon-associated genes, and the higher pro-inflammatory cytokine response in isolated primary PGLYRP4KO vs. WT cells. This phenotype is underlined by changes in the complexity and composition of the caecal microbiota of PGLYRP4KO compared to WT mice. Strikingly, we provided evidence, by cohousing and stable transfer of the respective WT or PGLYRP4KO mice microbiota into germfree WT mice, that the changes of the microbiota are responsible for the improved clearance of S. pneumoniae lung infection. In conclusion, the deficiency of PGLYRP4, a known antibacterial protein, leads to changes in the gut microbiota. Thus, alterations in the microbiota can change the susceptibility to S. pneumoniae lung infection independently of the host genotype.

Peptidoglycan Recognition Protein 2 Regulates Neutrophil Recruitment Into the Lungs After Streptococcus pneumoniae Infection. Front Microbiol 2019; 10:199.

Abstract
Peptidoglycan (PGN) recognition proteins (PGLYRPs) are a highly conserved group of host defense proteins in insects and mammals that sense bacterial cell wall PGN and act bactericidally or cleave PGN by amidase function. Streptococcus (S.) pneumoniae is one of the top five killers worldwide and causes, e.g., pneumonia, endocarditis, meningitis and sepsis. S. pneumoniae accounts for approximately 1.5–2 million deaths every year. The risk of antibiotic resistance and a general poor prognosis in young children and elderly people have led to the need for new treatment approaches. To the best of our knowledge, there is no report on the relevance of PGLYRP2 in lung infections. Therefore, we infected mice deficient for PGLYRP2 transnasally with S. pneumoniae and examined the innate immune response in comparison to WT animals. As expected, PGLYRP2-KO animals had to be sacrificed earlier than their WT counterparts, and this was due to higher bacteremia. The higher bacterial load in the PGLYRP2-KO mice was accomplished with lower amounts of proinflammatory cytokines in the lungs. This led to an abolished recruitment of neutrophils into the lungs, the spread of bacteria and the subsequent aggravated course of the disease and early mortality of the PGLYRP2-KO mice. These data suggest a substantial role of PGLYRP2 in the early defense against S. pneumoniae infection, and PGLYRP2 might also affect other infections in the lungs.

Abstract
The sensitivity of MDA-MB231 breast cancer cells to the effects of pharmacological agents was evaluated by their motility and viability. Dexamethasone, doxorubicin, or docetaxel administered separately in their effective concentration suppressed cell motility (in 16 h) and caused cell death (in 48 h). The strength of the effects increased in the following order: dexa methasone<doxorubicin≤docetaxel. The combined effects of the drugs were multidirectional: the total effect of dexamethasone and doxorubicin combination was inferior to their separate effect, while the effect of dexamethasone and docetaxel surpassed their individual effects. The combination of dexamethasone, doxorubicin, and docetaxel allowed negating the negative reciprocal interactions between dexamethasone and doxorubicin. The studying of the mechanisms underlying the observed phenomena attested to a potential role of S100A4 in the regulation of MDA-MB231 cells to the studied drugs.

Abstract
Pattern recognition receptors (PRRs) are employed in insects to defend against infectious pathogens by triggering various immune responses. Peptidoglycan recognition proteins (PGRPs), a vital family of PRRs, are widely distributed and highly conserved from vertebrates to invertebrates. To date, five PGRP genes have been identified in Antheraea pernyi, but their biochemical roles still remain unknown. In this study, we focused on the immune functions of PGRP-SA in A. pernyi (ApPGRP-SA), which was confirmed to be immune-related according to its significantly up-regulated expression level post microbial injection. In addition, the binding properties of ApPGRP-SA were investigated using a recombinant protein produced in a prokaryotic expression system, revealing that rApPGRP-SA displayed a multi-binding ability to various microbes, including the Gram-positive bacteria Staphylococcus aureus and Micrococcus luteus, Gram-negative bacteria Escherichia coli and Pseudomonas aeruginosa, and fungus Candida albicans, together with their surface pathogen associated molecular patterns (PAMPs). Further studies showed that after recognition, the mixture of rApPGRP-SA/PAMP remarkably stimulated prophenoloxidase (PPO) activation in the hemolymph of A. pernyi in vitro, while the ds-PGRP-SA-treated hemolymph exhibited a lower sensitivity to PAMPs in comparison to the native sample. Moreover, the transcriptional level of the three antimicrobial peptides was also decreased in PGRP-SA knock-down larvae in response to immune-challenge. In summary, we conclude that ApPGRP-SA is a novel identified PGRP in A. pernyi that might act as a broad-spectrum pattern recognition receptor and is involved in the PPO activation system as well as antimicrobial peptide production.

Abstract
Recently we have found that cytokine IL-2 and innate immunity protein Tag7 activate cytotoxic lymphocytes that kill HLA-negative tumor cells, inducing both apoptosis and necroptosis. Here we decrypt the processes, taking part in necroptosis execution after FasL-Fas interaction. Necroptosis begins with RIPK1 activation and necrosome formation. Subsequent activation of MLKL results in the increase of Ca2+ level in the cell and activation of Ca2+-dependent enzymes causing lysosomal membrane permeabilization and the release of cathepsins to the cytosol. STAT3 translocation to the mitochondria and binding to a component of the respiratory chain complex I causes ROS accumulation. We have shown that transduction of necroptotic signal via TNFR1 and Fas has many common points. It is known that apoptosis plays a major role in physiological cell death; however, under pathological conditions necroptosis is very common. That is why the detailed mechanisms of FasL-Fas necroptosis can help in understanding the processes of elimination of tumor cells that have blocked apoptosis signal transduction.

Abstract
Members of the 70 kDa stress protein family are found in nearly all subcellular compartments of nucleated cells where they fulfil a number of chaperoning functions. Heat shock protein 70 (HSP70), also termed HSPA1A, the major stress-inducible member of this family is overexpressed in a large variety of different tumour types. Apart from its intracellular localization, a tumour-selective HSP70 membrane expression has been determined. A membrane HSP70–positive tumour phenotype is associated with aggressiveness and therapy resistance, but also serves as a recognition structure for targeted therapies. Furthermore, membrane-bound and extracellularly residing HSP70 derived from tumour cells play pivotal roles in eliciting anti-tumour immune responses. Herein, we want to shed light on the multiplicity of different activities of HSP70, depending on its intracellular, membrane and extracellular localization with the goal to use membrane HSP70 as a target for novel therapies including nanoparticle-based approaches for the treatment of cancer. This article is part of the theme issue ‘Heat shock proteins as modulators and therapeutic targets of chronic disease: an integrated perspective’.

Abstract
In part as a result of the production of an enterotoxin, Staphylococcus aureus is a highly infectious pathogen and is a considerable threat to food hygiene and safety. Clinical mastitis models were established by S. aureus nipple-tube perfusion. The influence of mastitis on the mammary-gland-tissue proteomic profile was investigated using isobaric tags for relative and absolute quantitation. In this study, healthy and mastitic tissues from different mammary-gland areas of the same dairy cows were screened, and differentially expressed proteins were identified. Bioinformatic analysis identified proteins related to the inflammation and immunization of dairy cows. Histology, immunoblotting, and immunohistochemical-staining analyses were used to determine the expression of PGLYRP1 and PTX3 proteins in the acquired mammary-gland-tissue samples. PGLYRP1 and PTX3 in mastitic mammary glands may be associated with tissue damage and immune responses to late stages of infection. This further contributes to the understanding of the molecular theory of the treatment of mastitis caused by S. aureus.

Abstract
We have shown that in the human peripheral blood cells, the innate immunity protein Tag7 can activate a subpopulation of CD3+CD4+CD25+ cells, which have antitumor activity. These cells can induce lysis of HLA-negative tumor cell lines. The Hsp70 stress molecule on the surface of the tumor cells is used as a recognition target, while the Tag7 protein on the lymphocyte membrane acts as a receptor for Hsp70. We have also demonstrated that this subpopulation of the CD4+CD25+ cells is CD127 positive and hence is not the Treg cells. Our data suggest that this subpopulation of cells is identical to the CD4+CD25+ lymphocytes, which are activated in the leukocyte pool by the IL-2 cytokine.

Abstract
S100A4 is a Ca2+-binding protein that performs an important role in metastasis. It is also known for its antitumor functions. S100A4 is expressed by a specialized subset of CD4+CD25+ lymphocytes and is present on those cell's membranes along with peptidoglycan recognition proteins (PGRPs). There, by interacting with major heat shock protein Hsp70, S100A4 plays an important cytotoxic role. The resulting stably formed complex of PGRPs, S100A4 and Hsp70 is required for the identification and binding between a lymphocyte and a target cell. Here, we investigated the S100A4 functions in CD4+CD25+PGRPs+S100A4+ lymphocyte cytotoxicity against target cells. We demonstrated that those lymphocytes do not form a stable complex with the tumor target cells that themselves have S1004A on their surface. That observation can be explained by our finding that S100A4 precludes the formation of a stable complex between PGRPs, S100A4 (on the lymphocytes' surface), and Hsp70 (on the target cells' surface). The decrease in S100A4 level in CD4+CD25+PGRPs+S100A4+ lymphocytes inhibits their cytotoxic activity, while the addition of S100A4 in the medium restores it. Thus, the resistance of target cells to CD4+CD25+PGRPs+ S100A4+ lymphocyte cytotoxicity depends on their S100A4 expression level and can be countered by S100A4 antibodies.

Abstract
Pneumococci frequently cause community-acquired pneumonia, a disease with high mortality rates, particularly in young children and in the elderly. Endogenous antimicrobial peptides and proteins such as PGLYRP3 may contribute to the progression and outcome of this disease. Since increasing antibiotic resistant strains occur all over the world, these endogenous antimicrobial molecules are interesting new targets for future therapies. In this study, the expression pattern of PGLYRP3 was analyzed in alveolar epithelial cells, alveolar macrophages and neutrophils. Additionally, the function of PGLYRP3 during Streptococcus pneumoniae-induced pneumonia was investigated in a murine pneumococcal pneumonia model using PGLYRP3KO mice. PGLYRP3 is expressed in all selected cell types but pneumococcus-dependent induction of PGLYRP3 was observed only in neutrophils and alveolar macrophages. Interestingly, there were no significant differences in the bacterial loads within the lungs, the blood or the spleens, in the cytokine response, the composition of immune cells and the histopathology between wild type and PGLYRP3KO mice. Finally, we could neither observe significant differences in the clinical symptoms nor in the overall survival. Collectively, PGLYRP3 seems to be dispensable for the antibacterial defense during pneumococcal pneumonia.

Abstract
The discovery of new chemokines that induce the migration of lymphocytes to the infection site is important for the targeted search for therapeutic agents in immunotherapy. We recently showed that Tag7 (PGLYRP1), an innate immunity protein, forms a stable complex with the Ca2+ -binding protein Mts1 (S100A4), which is able to induce lymphocyte movement, although the individual Tag7 and Mts1 do not have this activity. The purpose of this study is to identify receptors that induce the migration of lymphocytes along the concentration gradient of the Tag7-Mts1 complex, and the components of this complex capable of interacting with these receptors. The study investigated the migration of human PBMC under the action of the Tag7-Mts1complex. PBMC of healthy donors were isolated using a standard Ficoll-Hypaque gradient centrifugation procedure. It has been established that the movement of PBMC along the concentration gradient of the Tag7-Mts1 complex is induced by the classical chemotactic receptors CCR5 and CXCR3. It has been shown that only Mts1 is able to bind to the extracellular domain of CCR5, however, this binding is not enough to induce cell movement. A comparative analysis of the primary and 3D structures of the three proteins revealed the homology of the amino acid sequence fragments of the Tag7-Mts1 protein complex with different sites of the CCR5 receptor ligand - MIP1α protein. In conclusion, it should be noted that the Tag7-Mts1 complex can be considered as a new ligand of the classical chemotactic receptors CCR5 and CXCR3.

Abstract
The innate immunity protein Tag7 (PGRP-S, PGLYRP1) is involved in antimicrobial and antitumor defense. As shown in our previous studies, Tag7 specifically interacts with the major heat shock protein Hsp70 to form a stable Tag7-Hsp70 complex with cytotoxic activity against tumor cells. A stable complex of Tag7 with the calcium-binding protein Mts1 (S100A4) stimulates migration of lymphocytes. Moreover, Tag7 can activate cytotoxic lymphocytes that recognize and kill HLA-negative tumor cells. Here, we have shown that Tag 7 treatment of human peripheral blood mononuclear cells (PBMCs) results in activation of different cytotoxic lymphocyte populations-natural killer (NK) cells and CD8+ NKG2D+ T lymphocytes-that kill Moloney murine leukemia virus (MMLV) infected SC-1 cells using different mechanisms of cell death induction. This mechanism in NK cells is based on the release of granzymes, which activate apoptosis in target cells, while CD8+ NKG2D+ T lymphocytes recognize the noncanonical MicA antigen on the surface of virus-containing cells and kill them via the FasL-Fas interaction, triggering the apoptotic or necroptotic cell death pathway. Preliminary incubation of PBMCs with virus-infected cells and following incubation with Tag7 results in activation of lymphocytes with a different phenotype. These lymphocytes change the spectrum of target cells and the mechanism of cell death induction, and their interaction with target cells is not species-specific. © 2017 IUBMB Life, 69(12):971-977, 2017.

Abstract
Naïve non-activated lymphocytes are capable of releasing the chemoattractant complex Tag7-Mts1 and can migrate along the gradient of its concentration. After activation of these cells by IL-2, they acquire the abilities to kill tumor cells and to release the cytotoxic Tag7-Hsp70 complex, which is accompanied by a loss of both the Tag7-Mts1-mediated lymphocyte chemotaxis and the ability to release this chemoattractant into the conditioned medium.
