Abstract
Unconventional T cells show distinct and unique features during antigen recognition as well as other immune responses. Their decrease in frequency is associated with various autoimmune disorders, allergy, inflammation, and cancer. The landscape frequency of the unconventional T cells altogether (iNKT, γδ T, and MAIT) is largely unestablished leading to various challenges affecting diagnosis and research in this field. In this study, we have established the age group–wise frequency of iNKT, γδ T, and MAIT cells altogether on a total of 203 healthy adult samples of the Caucasian population. The results revealed that iNKT cells were 0.095%, γδ T cells were 2.175%, and MAIT cells were 2.99% of the total T cell population. γδ and MAIT cell frequency is higher in younger age groups than elderly; however, there is no statistically significant difference in the frequency of iNKT cells. Furthermore, γδ and MAIT cells were negatively correlating with age, supporting immunosenescence, unlike iNKT cells. Our finding could be used for further age-wise investigation of various pathological conditions such as cancer and their prognosis, autoimmune diseases and their pathogenicity.

Abstract
The involvement of leukocytes in the pathophysiology of DR has mostly examined the role of monocytes and neutrophils with little emphasis on other immune cell types. In this study, we determined the systemic alterations in T cell subsets, myeloid cell types, NK cells, and NKT cells in the streptozotocin (STZ) mouse model of diabetic retinopathy (DR), and the role of NKT cells on retinal leukostasis and permeability changes. C57BL/6 J mice were made diabetic with 60 mg/kg dose of STZ given for 5-days. Flow cytometry assay measured the frequency of leukocyte subsets in the peripheral blood, spleen, and bone marrow of STZ- and vehicle-treated C57BL/6 J mice. Our results showed an increased proportion of memory CD8 T cells and interferon-gamma (IFN-γ) secreting CD8 T cells in the bone marrow of STZ-treated compared to control mice. Subsequently, increased production of inflammatory monocytes in the bone marrow and an enhanced frequency of CD11b + cells in the diabetic retina were seen in STZ-treated compared to control mice. The diabetic mice also exhibited a decrease in total NKT and CD4+NKT cells. A monoclonal antibody-based approach depleted NKT cells from STZ-treated mice, followed by measurements of retinal vascular permeability and leukostasis. The depletion of NKT cells in STZ-treated mice resulted in a significant increase in vascular permeability in the retinal tissue. Together, our results strongly imply the involvement of NKT cells in regulating the pathophysiology of the diabetic retina.

Abstract
iNKT (invariant natural killer T) cells are unconventional immunoregulatory T cells which contribute to B cell maturation, antibody and cytokine production. iNKT cells are implicated in the control of autoimmune inflammation in different disorders. For bullous pemphigoid (BP), the most frequent bullous autoimmune dermatosis, the role of iNKT cells has not yet been studied. We, therefore, aimed at investigating the frequency of iNKT cells in peripheral blood and biopsies from lesional and non-lesional skin from patients with BP and controls. Circulating CD3+iTCR+ iNKT cells were assessed by flow cytometry in peripheral blood from 30 patients with BP and from 29 controls (19 patients with skin tumors and 10 healthy controls). In 34 lesional and 13 non-lesional skin biopsies from BP patients and 17 biopsies from control individuals the number of Vα24+Vβ11+ iNKT cells was investigated by immunofluorescence staining. BP patients showed a significantly lower frequency of circulating iNKT cells compared to the control group. Patients with severe disseminated blistering tended to display lower iNKT cell numbers than patients with moderate disease severity. In lesional skin of BP patients, an enrichment of iNKT cells was detected compared to skin biopsies from controls. Similarly to control biopsies, non-lesional biopsies of BP patients contained only few iNKT cells. In conclusion, the deficiency of circulating iNKT cells associated with enrichment at the site of cutaneous inflammation suggests that iNKT cells may play a pathophysiologically relevant role in BP.

Abstract
AIM Proteomics has the potential to enhance early identification of beta-cell dysfunction, in conjunction with monitoring the various stages of type 2 diabetes onset. The most routine method of assessing pancreatic beta-cell function is an oral glucose tolerance test, however this method is time consuming and carries a participant burden. The objectives of this research were to identify protein signatures and pathways related to pancreatic beta-cell function in fasting blood samples. METHODS Beta-cell function measures were calculated for MECHE study participants who completed an oral glucose tolerance test and had proteomic data (n = 100). Information on 1,129 protein levels was obtained using the SOMAscan assay. Receiver operating characteristic curves were used to assess discriminatory ability of proteins of interest. Subsequent in vitro experiments were performed using the BRIN-BD11 pancreatic beta-cell line. Replication of findings were achieved in a second human cohort where possible. RESULTS Twenty-two proteins measured by aptamer technology were significantly associated with beta-cell function/HOMA-IR while 17 proteins were significantly associated with the disposition index (p ≤ 0.01). Receiver operator characteristic curves determined the protein panels to have excellent discrimination between low and high beta-cell function. Linear regression analysis determined that beta-endorphin and IL-17F have strong associations with beta-cell function/HOMA-IR, β = 0.039 (p = 0.005) and β = -0.027 (p = 0.013) respectively. Calcineurin and CRTAM were strongly associated with the disposition index (β = 0.005 and β = 0.005 respectively, p = 0.012). In vitro experiments confirmed that IL-17F modulated insulin secretion in the BRIN-BD11 cell line, with the lower concentration of 10 ng/mL significantly increasing glucose stimulated insulin secretion (p = 0.043). CONCLUSIONS Early detection of compromised beta-cell function could allow for implementation of nutritional and lifestyle interventions before progression to type 2 diabetes.

Abstract
Adoptive cellular therapy has evolved into a powerful force in the battle against cancer, holding promise for curative responses in patients with advanced and refractory tumors. Autologous T cells, reprogrammed to target malignant cells via the expression of a chimeric antigen receptor (CAR) represent the frontrunner in this approach. Tremendous clinical regressions have been achieved using CAR-T cells against a variety of cancers both in numerous preclinical studies and in several clinical trials, most notably against acute lymphoblastic leukemia, and resulted in a very recent United States Food and Drug Administration approval of the first CAR-T-cell therapy. In most studies CARs are transferred to conventional αβT cells. Nevertheless, transferring a CAR into different cell types, such as γδT cells, natural killer cells, natural killer T cells, and myeloid cells has yet received relatively little attention, although these cell types possess unique features that may aid in surmounting some of the hurdles CAR-T-cell therapy currently faces. This review focuses on CAR therapy using effectors beyond conventional αβT cells and discusses those strategies against the backdrop of developing a safe, powerful, and durable cancer therapy.

Abstract
Class I-restricted T cell-associated molecule (CRTAM) is an activation marker expressed on the cell surface of activated invariant natural killer T (iNKT) cells, CD8+ T cells, and a small subset of CD4+ T cells. CRTAM has also been associated with a proinflammatory profile in murine CD4+ T cells. However, CRTAM has not been thoroughly explored in human cells. This work focused on evaluating CRTAM expression in human iNKT lymphocytes after activation with α-galactosylceramide, its widely used specific glycolipid antigen. We also analyzed the involvement of costimulatory molecules in CRTAM expression and whether CRTAM expression is associated with a specific effector cytokine profile. We found that the signal produced by invariant T cell receptor (iTCR) engagement with α-galactosylceramide is sufficient to trigger CRTAM expression on human iNKT cells after 18 h of stimulation. Moreover, we observed a clear association between CRTAM expression and IFN-γ production in iNKT cells from healthy subjects and patients with type 1 diabetes. However, blocking the engagement of costimulatory molecules, such as CD40, CD80, and CD86, did not modify CRTAM expression. These results indicate that CRTAM may also play a role in triggering the production of IFN-γ in human iNKT cells and that CRTAM could be used as a marker to identify these inflammatory cells.
