Abstract
Crosstalk between mast cells (MCs) and T lymphocytes (TLs) releases specific signals that create an environment conducive to tumor development. Conversely, they can protect against cancer by targeting tumor cells for destruction. Although their role in immunity and cancer is complex, their potential in anticancer strategies is often underestimated. When peripheral MCs are activated, they can affect cancer development. Tumor-infiltrating TLs may malfunction and contribute to aggressive cancer and poor prognoses. One promising approach for cancer patients is TL-based immunotherapies. Recent reports suggest that MCs modulate TL activity in solid tumors and may be a potential therapeutic layer in multitargeting anticancer strategies. Pharmacologically modulating MC activity can enhance the anticancer cytotoxic TL response in tumors. By identifying tumor-specific targets, it has been possible to genetically alter patients' cells into fully humanized anticancer cellular therapies for autologous transplantation, including the engineering of TLs and MCs to target and kill cancer cells. Hence, recent scientific evidence provides a broader understanding of MC-TL activity in cancer.

Identification of CD160-TM as a tumor target on triple negative breast cancers: possible therapeutic applications. Breast Cancer Res 2024; 26:28.

Abstract
BACKGROUND Despite major therapeutic advances, triple-negative breast cancer (TNBC) still presents a worth prognosis than hormone receptors-positive breast cancers. One major issue relies in the molecular and mutational heterogeneity of TNBC subtypes that is reinforced by the absence of reliable tumor-antigen that could serve as a specific target to further promote efficient tumor cell recognition and depletion. CD160 is a receptor mainly expressed by NK lymphocytes and presenting two isoforms, namely the GPI-anchored form (CD160-GPI) and the transmembrane isoform (CD160-TM). While CD160-GPI is constitutively expressed on resting cells and involved in the generation of NK cells' cytotoxic activity, CD160-TM is neo-synthesized upon activation and promotes the amplification of NK cells' killing ability. METHODS CD160 expression was assessed by immunohistochemistry (IHC) and flow cytometry on TNBC patient biopsies or cell lines, respectively. Antibody (Ab)-mediated tumor depletion was tested in vitro by performing antibody-dependent cell cytotoxicity (ADCC) and phagocytosis (ADCP) assays, and in vivo on a TNBC mouse model. RESULTS Preliminary data obtained by IHC on TNBC patients' tumor biopsies revealed an unconventional expression of CD160 by TNBC tumor cells. By using a specific but conformation-dependent anti-CD160-TM Ab, we established that CD160-TM, but not CD160-GPI, was expressed by TNBC tumor cells. A conformation-independent anti-CD160-TM mAb (22B12; muIgG2a isotype) was generated and selected according to pre-defined specificity and functional criterions. In vitro functional assays demonstrated that ADCC and ADCP could be induced in the presence of 22B12, resulting in TNBC cell line apoptosis. The ability of 22B12 to exert an in vivo anti-tumor activity was also demonstrated on a TNBC murine model. CONCLUSIONS Our data identify CD160-TM as a tumor marker for TNBC and provide a rational for the use of anti-CD160-TM antibodies as therapeutic tools in this tumor context.

Abstract
CD160 is a glycosylphosphatidylinositol (GPI)-anchored cell surface glycoprotein expressed on cytotoxic natural killer (NK) cells and T-cell subsets. It plays a crucial role in the activation of NK-cell cytotoxicity and cytokine production. It also modulates the immune system and is involved in some pathologies, such as cancer. CD160 is abnormally expressed in B-cell chronic lymphocytic leukemia (CLL) but not expressed in normal B lymphocytes. Its expression in CLL enhances tumor cell proliferation and resistance to apoptosis. CD160 is also a potential prognostic marker for the detection of minimal residual disease (MRD) in CLL, which is important for the clinical management of CLL, the prevention of disease relapse, and the achievement of complete remission. In this review, we present an overview of CD160 and its involvement in the pathophysiology of CLL. We also discuss its use as a prognostic marker for the assessment of MRD in CLL.

Abstract
Melanoma is responsible for 90% of skin cancer-related deaths. Major therapeutic advances have led to a considerable improvement in the prognosis of patients, with the development of targeted therapies (BRAF or MEK inhibitors) and immunotherapy (anti-CTLA-4 or -PD-1 antibodies). However, the tumor constitutes an immunosuppressive microenvironment that prevents the therapeutic efficacy and/or promotes the development of secondary resistances. CD160 is an activating NK-cell receptor initially described as delineating the NK and CD8+T-cell cytotoxic populations. Three forms of CD160 have been described: (1) the GPI isoform, constitutively expressed and involved in the initiation of NK-cells' cytotoxic activity, (2) the transmembrane isoform, neo-synthesized upon cell activation, allowing the amplification of NK cells' cytotoxic functions and (3) the soluble form, generated after cleavage of the GPI isoform, which presents an immuno-suppressive activity. By performing immunohistochemistry analyses, we observed a strong expression of CD160 at the primary cutaneous tumor site of melanoma patients. We further demonstrated that melanoma cells express CD160-GPI isoform and constitutively release the soluble form (sCD160) into the tumor environment. sCD160 was shown to inhibit the cytotoxic activity of NK-cells towards their target cells. In addition, it was found in the serum of melanoma patients and associated with increased tumor dissemination. Altogether these results support a role for sCD160 in the mechanisms leading to the inhibition of anti-tumor response and immune surveillance in melanoma.

Abstract
Background T cell exhaustion compromises antitumor immunity, and a sustained elevation of co-inhibitory receptors is a hallmark of T cell exhaustion in solid tumors. Similarly, upregulation of co-inhibitory receptors has been reported in T cells in hematological cancers such as chronic lymphocytic leukemia (CLL). However, the role of CD160, a glycosylphosphatidylinositol-anchored protein, as one of these co-inhibitory receptors has been contradictory in T cell function. Therefore, we decided to elucidate how CD160 expression and/or co-expression with other co-inhibitory receptors influence T cell effector functions in patients with CLL. Methods We studied 56 patients with CLL and 25 age-matched and sex-matched healthy controls in this study. The expression of different co-inhibitory receptors was analyzed in T cells obtained from the peripheral blood or the bone marrow. Also, we quantified the properties of extracellular vesicles (EVs) in the plasma of patients with CLL versus healthy controls. Finally, we measured 29 different cytokines, chemokines or other biomarkers in the plasma specimens of patients with CLL and healthy controls. Results We found that CD160 was the most upregulated co-inhibitory receptor in patients with CLL. Its expression was associated with an exhausted T cell phenotype. CD160+CD8+ T cells were highly antigen-experienced/effector T cells, while CD160+CD4+ T cells were more heterogeneous. In particular, we identified EVs as a source of CD160 in the plasma of patients with CLL that can be taken up by T cells. Moreover, we observed a dominantly proinflammatory cytokine profile in the plasma of patients with CLL. In particular, interleukin-16 (IL-16) was highly elevated and correlated with the advanced clinical stage (Rai). Furthermore, we observed that the incubation of T cells with IL-16 results in the upregulation of CD160. Conclusions Our study provides a novel insight into the influence of CD160 expression/co-expression with other co-inhibitory receptors in T cell effector functions in patients with CLL. Besides, IL-16-mediated upregulation of CD160 expression in T cells highlights the importance of IL-16/CD160 as potential immunotherapy targets in patients with CLL. Therefore, our findings propose a significant role for CD160 in T cell exhaustion in patients with CLL.

Abstract
Malaria is a life-threatening infectious disease, affecting over 250 million individuals worldwide each year, eradicating malaria has been one of the greatest challenges to public health for a century. Growing resistance to anti-parasitic therapies and lack of effective vaccines are major contributing factors in controlling this disease. However, the incomplete understanding of parasite interactions with host anti-malaria immunity hinders vaccine development efforts to date. Recent studies have been unveiling the complexity of immune responses and regulators against Plasmodium infection. Here, we summarize our current understanding of host immune responses against Plasmodium-derived components infection and mainly focus on the various regulatory mechanisms mediated by recent identified immune regulators orchestrating anti-malaria immunity.

Abstract
The transfer and development of chronic hepatitis B virus (HBV) infection is associated with the T cell immune response, therefore investigating the key regulators of cell immune response is needed to improve chronic HBV treatment. Blood samples from patients with chronic HBV infection were used to confirm the correlation between HBV infection stage and CD160 receptor expression levels in CD8+ T cells, the CD8+ T cells are used to research the mechanism of T cell immune response modulation, moreover, C3H/HeN mice with reduced CD160 expression levels were used to investigate the association between long non-coding (lnc)RNA-CD160 and HBV infection. Long non-coding (lnc)RNA-CD160 and histone-modification enzyme gene histone deacetylase 11 (HDAC11) expression levels were negatively associated with CD160 expression. lncRNA-CD160 can inhibit the secretion of IFN-γ and TNF-α through HDAC11 recruitment and bind to HDAC11 to form a complex on the promoters of IFN-γ and TNF-α. The HDAC11, IFN-γ and TNF-α form a complex and enhance the methylation of H3K9Me1, chromatin changes into the heterochromatin and the transcription of IFN-γ and TNF-α is blocked; moreover, the HDAC11/IFN-γ/TNF-α complex can also inhibit the secretion of IFN-γ and TNF-α in CD160− CD8+ T cells and suppresses the function of CD8+ T cells. Furthermore, small interfering RNA targeting lncRNA-CD160 can block HBV infection progression. lncRNA-CD160 acts as an immune suppressive factor and is expressed at a high level in peripheral blood CD8+ T cells of HBV infected patients. Furthermore, high expression levels of lncRNA-CD160 can contribute to the inhibition of IFN-γ and TNF-α secretion in CD8+ T cells and decrease the immune response of CD8+ T cells. Therefore, lncRNA-CD160 may become a new target for immunotherapy of chronic HBV infection in the future and may provide a new therapeutic strategy for the treatment of HBV infection.

Abstract
CD8+ T cells are key players during infection with the malaria parasite Plasmodium berghei ANKA (PbA). While they cannot provide protection against blood-stage parasites, they can cause immunopathology, thus leading to the severe manifestation of cerebral malaria. Hence, the tight control of CD8+ T cell function is key in order to prevent fatal outcomes. One major mechanism to control CD8+ T cell activation, proliferation and effector function is the integration of co-inhibitory and co-stimulatory signals. In this study, we show that one such pathway, the HVEM-CD160 axis, significantly impacts CD8+ T cell regulation and thereby the incidence of cerebral malaria. Here, we show that the co-stimulatory molecule HVEM is indeed required to maintain CD8+ T effector populations during infection. Additionally, by generating a CD160-/- mouse line, we observe that the HVEM ligand CD160 counterbalances stimulatory signals in highly activated and cytotoxic CD8+ T effector cells, thereby restricting immunopathology. Importantly, CD160 is also induced on cytotoxic CD8+ T cells during acute Plasmodium falciparum malaria in humans. In conclusion, CD160 is specifically expressed on highly activated CD8+ T effector cells that are harmful during the blood-stage of malaria.

Abstract
BACKGROUND Staphylococcus aureus, one of the most important pathogens, is heavily associated with allergy. S. aureus and its toxins interact with eosinophils through CD48, a GPI-anchored receptor important in allergy mainly as expressed by the eosinophils (mCD48). CD48 can exist in a soluble form (sCD48). Our aim was to investigate SEB-induced regulation of eosinophil CD48 and the possible formation and role of sCD48 in SEB-mediated eosinophil activation in vitro and in vivo. METHODS Human peripheral blood eosinophils were activated by SEB with or without inhibitors for phospholipases (PL) (-C or -D), or cycloheximide, or brefeldin A. We evaluated eosinophil activation (CD11b expression or EPO/IL-8 release), mCD48 (flow cytometry), sCD48 (ELISA), SEB binding to sCD48 (ELISA), and chemotaxis toward SEB. C57BL/6 mice were pre-injected (ip.) with sCD48, and then, peritonitis was induced by SEB injection; peritoneal lavages were collected after 48 h and analyzed by flow cytometry and ELISA. RESULTS SEB-activated human eosinophils formed sCD48, directly correlating with CD11b expression, through cell-associated PL-C and -D. mCD48 remained stable due to up-regulation in CD48 transcription and cellular trafficking. sCD48 bound to SEB and down-regulated SEB stimulatory effects on eosinophils as assessed by EPO and IL-8 release and eosinophil chemotaxis toward SEB. sCD48 showed anti-inflammatory activity in a SEB-induced mouse peritonitis model. CONCLUSIONS SEB regulates CD48 dynamics on eosinophils. Our data indicate sCD48 as a SEB-induced 'decoy' receptor derived from eosinophil and therefore as a potential anti-inflammatory tool in S. aureus-induced eosinophil inflammation often associated with allergy.

Abstract
Human skin diseases are various and induce chronic inflammatory disorders, including psoriasis, atopic dermatitis and certain forms of ichthyosis. Psoriasis is a chronic inflammatory skin disease characterized by circumscribed, red, thickened plaques. Regulation of the balance between growth, differentiation and death is critical to keratinocytes; when altered, epidermal keratinocytes undergo hyperproliferation, abnormal differentiation and inflammatory infiltration. In the present study, we focused on the effects of resveratrol, found in red wine and peanuts, on the cell death of keratinocytes. We additionally studied the mechanism of resveratrol on Sirt1, a class III histone deacetylase, and Akt phosphorylation. Resveratrol caused apoptosis and increased Sirt1 expression in human HaCaT keratinocytes, following a decrease in the p62 protein level. Inhibition of Sirt1 by Sirt1 inhibitor restored cell viability and protein levels. Furthermore, we showed that resveratrol-induced Sirt1 blocked Akt phosphorylation. The present results indicated that resveratrol inhibited the Akt pathways by inducing Sirt1, thus leading to cell death. These data suggest that resveratrol-mediated activation of Sirt1 histone deacetylase may be a potential therapeutic target for skin diseases including psoriasis.

Abstract
Glycosylphosphatidylinositol (GPI) anchors are critical for the membrane attachment of a wide variety of essential signaling and cell adhesion proteins. The GPI anchor is a complex glycolipid structure that utilizes glycosylphosphatidylinositol-mannosyltransferases (GPI-MTs) for the addition of three core mannose residues during its biosynthesis. Here, we demonstrate that Drosophila GPI-MT2 is required for the GPI-mediated membrane attachment of several GPI-anchored proteins, including the photoreceptor-specific cell adhesion molecule, chaoptin. Mutations in gpi-mt2 lead to defects in chaoptin trafficking to the plasma membrane in Drosophila photoreceptor cells. In gpi-mt2 mutants, loss of sufficient chaoptin in the membrane leads to microvillar instability, photoreceptor cell pathology, and retinal degeneration. Finally, using site-directed mutagenesis, we have identified key amino acids that are essential for GPI-MT2 function and cell viability in Drosophila. Our findings on GPI-MT2 provide a mechanistic link between GPI anchor biosynthesis and protein trafficking in Drosophila and shed light on a novel mechanism for inherited retinal degeneration.
