Abstract
Nanomedicine could improve the treatment of diabetes by exploiting various therapeutic mechanisms through the use of suitable nanoformulations. For example, glucose-sensitive nanoparticles can release insulin in response to high glucose levels, mimicking the physiological release of insulin. Oral nanoformulations for insulin uptake via the gut represent a long-sought alternative to subcutaneous injections, which cause pain, discomfort, and possible local infection. Nanoparticles containing oligonucleotides can be used in gene therapy and cell therapy to stimulate insulin production in β-cells or β-like cells and modulate the responses of T1DM-associated immune cells. In contrast, viral vectors do not induce immunogenicity. Finally, in diabetic wound healing, local delivery of nanoformulations containing regenerative molecules can stimulate tissue repair and thus provide a valuable tool to treat this diabetic complication. Here, we describe these different approaches to diabetes treatment with nanoformulations and their potential for clinical application.

Abstract
Diabetes is a serious health issue that causes a progressive dysregulation of carbohydrate metabolism due to insufficient insulin hormone, leading to consistently high blood glucose levels. According to the epidemiological data, the prevalence of diabetes has been increasing globally, affecting millions of individuals. It is a long-term condition that increases the risk of various diseases caused by damage to small and large blood vessels. There are two main subtypes of diabetes: type 1 and type 2, with type 2 being the most prevalent. Genetic and molecular studies have identified several genetic variants and metabolic pathways that contribute to the development and progression of diabetes. Current treatments include gene therapy, stem cell therapy, statin therapy, and other drugs. Moreover, recent advancements in therapeutics have also focused on developing novel drugs targeting these pathways, including incretin mimetics, SGLT2 inhibitors, and GLP-1 receptor agonists, which have shown promising results in improving glycemic control and reducing the risk of complications. However, these treatments are often expensive, inaccessible to patients in underdeveloped countries, and can have severe side effects. Peptides, such as glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1), are being explored as a potential therapy for diabetes. These peptides are postprandial glucose-dependent pancreatic beta-cell insulin secretagogues and have received much attention as a possible treatment option. Despite these advances, diabetes remains a major health challenge, and further research is needed to develop effective treatments and prevent its complications. This review covers various aspects of diabetes, including epidemiology, genetic and molecular basis, and recent advancements in therapeutics including herbal and synthetic peptides.

Abstract
Breathing is crucial in life; nevertheless, the healthcare community often overlooks the health potential of breathing techniques. Conscious manipulation of breathing to achieve specific health goals is found in yoga, Qigong and Tai Chi. This paper reviews the value of breathing exercises as a foremost mechanism for promoting, recuperating and maintaining health. Practices involving breathing techniques are described, and their prophylactic or therapeutic characteristics are explored. The main goals of this review are: (i) to summarize the evidence supporting the hypothesis that breathing practices have a significant beneficial impact on human health; (ii) to provide a deeper understanding of traditional biofeedback practices, particularly yoga, Qigong and Tai Chi, and outline their focus on breathing techniques; (iii) to outline specific immune-related responses, relevant for COVID-19 disorders; and (iv) to call for committed attention and action from the scientific community and health agencies in promoting the implementation of a practical and costless health program based on breathing techniques. This review shows the health potentials of breathing practices and exercises, which, by having a high benefit-cost ratio, could be selected and implemented as a primary standard routine in public health programs.

Abstract
Diabetes mellitus (DM) underscores a rising epidemic orchestrating critical socio-economic burden on countries globally. Different treatment options for the management of DM are evolving rapidly because the usual methods of treatment have not completely tackled the primary causes of the disease and are laden with critical adverse effects. Thus, this narrative review explores different treatment regimens in DM management and the associated challenges. A literature search for published articles on recent advances in DM management was completed with search engines including Web of Science, Pubmed/Medline, Scopus, using keywords such as DM, management of DM, and gene therapy. Our findings indicate that substantial progress has been made in DM management with promising results using different treatment regimens, including nanotechnology, gene therapy, stem cell, medical nutrition therapy, and lifestyle modification. However, a lot of challenges have been encountered using these techniques, including their optimization to ensure optimal glycemic, lipid, and blood pressure modulation to minimize complications, improvement of patients' compliance to lifestyle and pharmacologic interventions, safety, ethical issues, as well as an effective delivery system among others. In conclusion, lifestyle management alongside pharmacological approaches and the optimization of these techniques is critical for an effective and safe clinical treatment plan.

Abstract
Arthritis is a genetic disorder characterized by bones and joint degradation assisted by severe pain and inflammation. It is evident by the studies that 0 candidate genes variations play vital role in its development and progression. Therefore, we investigated the genetic variation of TLR-8, TNF, and ESR-1α genes in the Pakistani population. A case-control study comprising 300 RA, 316 OA, and 412 control subjects was conducted. PCR-RFLP and direct sequencing methods were used for determining genetic variations. Analysis was performed by using PLINK and MEGA 6.0 software. Allelic and genetic frequencies of polymorphisms identified on rs3764879 (TLR-8), rs3764880 (TLR-8), rs5744080 (TLR-8), rs1800629 (TNF), rs2228480 (ESR-1α), and rs1451501590 (ESR-1α) were significantly varied among RA, OA, and controls. Novel functional mutations SCV000844945 and SCV000844946 on TLR-8 as well as a non-functional SCV000804801 and functional variation SCV000804802 on ESR-1α were also identified and reported for the first time in the studied population. Multiple site analyses indicated that polymorphisms on TLR-8 and ESR-1α genes were significant risk factors in disease onset to the next generation. In conclusion, TLR-08 and ESR-1α were significant in the onset of arthritis whereas the TNF was not found as a significant risk factor in the onset of RA and OA.

Abstract
<strong>Objective:</strong> Insulin insufficiency due to the reduced pancreatic beta cell number is the hallmark of diabetes, resulting in<br />an intense focus on the development of beta-cell replacement options. One approach to overcome the problem is to<br />search for alternative sources to induce insulin-producing cells (IPCs), the advent of mesenchymal stem cells (MSCs)<br />holds great promise for producing ample IPCs. Encapsulate the MSCs with alginate improved anti-inflammatory effects<br />of MSC treatment. This study aimed to evaluate the differentiation of wharton jelly-derived MScs into insulin producing<br />cells using alginate encapsulation.<br /><strong>Materials and Methods:</strong> In this experimental study, we established an efficient IPCs differentiation strategy of human<br />MSCs derived from the umbilical cord's Wharton jelly with lentiviral transduction of Pancreas/duodenum homeobox<br />protein 1 (PDX1) in a 21-day period using alginate encapsulation by poly-L-lysine (PLL) and poly-L-ornithine (PLO)<br />outer layer. During differentiation, the expression level of PDX1 and secretion of insulin proteins were increased.<br /><strong>Results:</strong> Results showed that during time, the cell viability remained high at 87% at day 7. After 21 days, the differentiated beta-like cells in microcapsules were morphologically similar to primary beta cells. Evaluation of the expression of PDX1 and INS by quantitative reverse transcriptase-polymerase chain reaction (qRT-PCR) on days 7, 14 and 21 of differentiation exhibited the highest expression on day 14. At the protein level, the expression of these two pancreatic markers was observed after PDX1 transduction. Results showed that the intracellular and extracellular insulin levels in the cells receiving PDX1 is higher than the control group. The current data showed that encapsulation with alginate by PLL and PLO outer layer permitted to increase the microcapsules' beta cell differentiation.<br /><strong>Conclusion</strong>: Encapsulate the transduced-MSCs with alginate can be applied in an in vivo model in order to do the further analysis.

Abstract
BACKGROUND Type 1 diabetes mellitus (T1DM) is an autoimmune disorder characterized by T cell-mediated self-destruction of insulin-secreting islet β cells. Management of T1DM is challenging and complicated especially with conventional medications. Gene therapy has emerged as one of the potential therapeutic alternatives to treat T1DM. This review primarily focuses on the current status and the future perspectives of gene therapy in the management of T1DM. A vast number of the studies which are reported on gene therapy for the management of T1DM are done in animal models and in preclinical studies. In addition, the safety of such therapies is yet to be established in humans. Currently, there are several gene level interventions that are being investigated, notably, overexpression of genes and proteins needed against T1DM, transplantation of cells that express the genes against T1DM, stem-cells mediated gene therapy, genetic vaccination, immunological precursor cell-mediated gene therapy and vectors. METHODS We searched the current literature through searchable online databases, journals and other library sources using relevant keywords and search parameters. Only relevant publications in English, between the years 2000 and 2018, with evidences and proper citations, were considered. The publications were then analyzed and segregated into several subtopics based on common words and content. A total of 126 studies were found suitable for this review. FINDINGS Generally, the pros and cons of each of the gene-based therapies have been discussed based on the results collected from the literature. However, there are certain interventions that require further detailed studies to ensure their effectiveness. We have also highlighted the future direction and perspectives in gene therapy, which, researchers could benefit from.

Abstract
In the past, the clinical therapy for autoimmune diseases, such as autoimmune polychondritis ear disease, was mostly limited to nonspecific immunosuppressive agents, which could lead to variable responses. Currently, gene therapy aims at achieving higher specificity and less adverse effects. This concept utilizes the adoptive transfer of autologous T cells that have been retrovirally transduced ex vivo to express and deliver immunoregulatory gene products to sites of autoimmune inflammation. In the animal model of collagen-induced autoimmune polychondritis ear disease (CIAPED), the adoptive transfer of IL-12p40-expressing collagen type II (CII)-specific CD4+ T-cell hybridomas resulted in a significantly lower disease incidence and severity compared with untreated or vector-only-treated animals. In vivo cell detection using bioluminescent labels showed that transferred CII-reactive T-cell hybridomas accumulated in the inflamed earlobes of the mice with CIAPED. In vitro analysis demonstrated that IL-12p40-transduced T cells did not affect antigen-specific T-cell activation or systemic anti-CII Ab responses. However, IL-12p40-transduced T cells suppressed IFN-γ and augmented IL-4 production, indicating their potential to act therapeutically by interrupting Th1-mediated inflammatory responses via augmenting Th2 responses. These results indicate that the local delivery of IL-12p40 by T cells could inhibit CIAPED by suppressing autoimmune responses at the site of inflammation.

Abstract
Dendritic cells (DCs) are important APCs able to induce both tolerance and immunity. Therefore, DCs are attractive targets for immune intervention. However, the ex vivo generation and manipulation of DCs at sufficient numbers and without changing their original phenotypic and functional characteristics are major obstacles. To manipulate DCs in vivo, we developed a novel DC-specific self-inactivating lentiviral vector system using the 5' untranslated region from the DC-STAMP gene as a putative promoter region. We show that a gene therapy approach with these DC-STAMP-lentiviral vectors yields long-term and cell-selective transgene expression in vivo. Furthermore, transcriptionally targeted DCs induced functional, Ag-specific CD4 and CD8 T cell tolerance in vivo, which could not be broken by viral immunization. Tolerized CTL were unable to induce autoimmune diabetes in a murine autoimmune model system. Therefore, delivering transgenes specifically to DCs by using viral vectors might be a promising tool in gene therapy.

Abstract
Traditional Chinese medicine, including herbal medicine and acupuncture, as one of the most important parts in complementary and alternative medicine (CAM), plays the key role in the formation of integrative medicine. Why do not the modern drugs targeting the specificity of diseases produce theoretical effects in clinical observation? Why does not the traditional Chinese medicine targeting the Zheng (syndrome) produce theoretical effects in clinic? There should have some reasons to combine Western medicine with Chinese herbal medicine so as to form the integrative medicine. During the integration, how to clarify the impact of CAM theory on Western medicine has become an emergent topic. This paper focuses on the exploration of the impact of theory of traditional Chinese medicine on the therapy of diseases in Western medicine.

Abstract
Although it is well known that genetic factors contribute significantly to the expression of systemic lupus erythematosus (SLE) it was only recently realized, through genome-wide searches, that the number of involved genes is rather large. The published information hints at two facts: first, the number of genomic loci identified in various diverse cohorts is large and not necessarily overlapping; and second, certain loci may be preferentially linked with specific clinical manifestations. The latter may ultimately lead to a better understanding of the nature of the clinical entity that we know as SLE, and identification of groups of patients prone to respond better to treatment or to develop significant adverse effects. Advances attained regarding the nature of the biochemical and molecular defects that underwrite the aberrant function of immune cells parallel the progress made on the genetic origin of the disease. The genetic links need to be connected with aberrant function of their products to validate their significance. It is expected that correction of molecular aberrations either medicinally or by gene therapy will provide the needed specific treatment for patients with SLE.

Abstract
Antigen-specific lymphocytes are involved in synovial proliferation within inflamed joints. Activated lymphocytes and synoviocytes from patients with rheumatoid arthritis express receptors that can bind TNF-related apoptosis-inducing ligand (TRAIL). A new study demonstrates that DCs pulsed with collagen and transduced with an adenovirus-based vector able to express TRAIL limit the incidence of arthritis in a model of collagen-induced arthritis and joint inflammation. These results suggest that gene-modified cell therapy represents a therapeutic option for systemic rheumatic diseases.

Abstract
Although systemic administration of neutralizing anti-TNF antibodies has been used successfully in treating rheumatoid arthritis, there is a potential for side effects. We transduced a collagen reactive T-cell hybridoma with tissue-specific homing properties to assess therapeutic effects of local delivery to inflamed joints of anti-TNF single-chain antibodies (scFv) by adoptive cellular gene therapy. Cell culture medium conditioned with 1 x 10(6) scFv producer cells/ml had TNF neutralizing capacity in vitro equivalent to 50 ng/ml anti-TNF monoclonal antibody. Adding a kappa chain constant domain to the basic scFv (construct TN3-Ckappa) gave increased in vitro stability and in vivo therapeutic effect. TN3-Ckappa blocked development of collagen-induced arthritis in DBA/1LacJ mice for >60 days. Transgene expression was detected in the paws but not the spleen of treated animals for up to 55 days postinjection. No significant variations in cell proliferation or cytokine secretion were found in splenocytes or peripheral lymphocytes. IL-6 expression was blocked in the diseased paws of mice in the scFv treatment groups compared to controls. In conclusion, we have shown that local expression of an anti-inflammatory agent blocks disease development without causing demonstrable systemic immune function changes. This is encouraging for the potential development of safe adoptive cellular therapies to treat autoimmunity.

Abstract
OBJECTIVE T cells from a majority of patients with systemic lupus erythematosus (SLE) display antigen receptor-mediated signaling aberrations associated with defective T cell receptor (TCR) zeta chain, a subunit of the TCR/CD3 complex. This study was undertaken to explore the possibility that forced expression of TCR zeta chain may reverse the known signaling abnormalities and defective interleukin-2 (IL-2) production in SLE T cells. METHODS Freshly isolated SLE T cells were transfected with TCR zeta chain construct in a eukaryotic expression vector at high efficiency, by a recently developed nucleoporation technique. Restoration of TCR/CD3-mediated signaling was studied in the zeta chain-transfected cells. RESULTS In SLE T cells transfected with TCR zeta chain, surface expression of TCR chain was increased and the TCR/CD3-induced increased free intracytoplasmic calcium concentration response was normalized, as was hyperphosphorylation of cellular substrates. Simultaneously, the previously noted increased expression of the Fc receptor gamma chain was diminished in SLE T cells transfected with the zeta chain expression vector, and the surface membrane clusters of cell signaling molecules were redistributed to a more continuous pattern. TCR zeta chain replacement also augmented the expression of diminished TCR/CD3-mediated IL-2 production in SLE T cells, associated with increased expression of the p65 subunit of nuclear factor kappaB in the nuclear fractions of these T cells. CONCLUSION These results suggest that reconstitution of deficient TCR zeta chain can reverse the TCR/CD3-mediated signaling abnormalities as well as the defective IL-2 production in T cells of patients with SLE.

Abstract
The recent identification of a number of molecular defects in T cells from patients with systemic lupus erythematosus (SLE) has raised expectations for gene replacement therapy as an option in the treatment of these diseases. In this report, we have adapted an electroporation-based technique to transfer successfully DNA to peripheral blood T cells from normal individuals and patients with systemic lupus erythematosus and rheumatoid arthritis. Transfection efficiency, judged by the percentage of live cells expressing green fluorescence after transfection with a pGFP (green fluorescence protein), reached 32 +/- 3% in normal, 13 +/- 3% in SLE, and 17 +/- 13% in RA T cells. The transfection efficiency was slightly higher in CD8+ than in CD4+ cells, and the cells maintained acceptable (75%) viability up to the fourth post-transfection day. SLE T cells have been shown to display low levels of the p65 subunit of the NF-kappaB transcription factor and decreased production of IL-2. Since NF-kappaB contributes to the transcriptional regulation of the IL-2 promoter, the effect of the forced replenishment of p65 on IL-2 transcription was tested. The low level of interleukin-2 promoter activity in SLE T cells increased to normal levels following transfection with cDNA encoding the NF-kappaB p65 subunit. Taken together, these results demonstrate the feasibility of transfection of T cells from SLE patients by electroporation and the reversal of decreased interleukin-2 promoter activity in SLE T cells, and are an early step toward gene therapy as a method of treatment for these individuals.

Abstract
BACKGROUND Gene therapy is an emerging field of biomedicine that has commanded considerable scientific and popular attention. The procedure involves the transfer of genes to patients for clinical benefit. Transferred genes can b e used for either reparative or pharmacological purposes. OVERVIEW In 1995, the first author and a colleague described the potential impact of gene therapy on dentistry, on the basis of initial studies of gene transfer applications to salivary glands, keratinocytes and cancer cells. Their conclusion was that gene therapy would have a significant impact on the nature of dental practice within 20 years. In this article, the authors consider research progress since 1995 and reexamine the earlier conclusion. PRACTICE IMPLICATIONS In the past six years, remarkable progress has been made in the field of gene therapy, including seven areas relevant to dental practice: bone repair, salivary glands, autoimmune disease, pain, DNA vaccinations, keratinocytes and cancer. While considerable problems remain, thus impeding the routine clinical use of gene transfer, gene therapy will have a pervasive and significant impact on areas of dental practice that are based in biological science. By 2015, this will translate into practitioners' having a wide range of novel biological treatment options for their patients.

Abstract
The ecdysteroid-responsive Drosophila melanogaster B(II) cell line is a prototypical homologous inducible gene expression system. A training set of 71 ecdysteroids, for which the -log(EC(50)) potencies in the ecdysteroid-responsive B(II) cell line were measured, was used to construct 4D-QSAR models. Four nearly equivalent optimum 4D-QSAR models, for two modestly different alignments, were identified (Q(2) = 0.76-0.80). These four models, together with two CoMFA models, were used in consensus modeling to arrive at a three-dimensional pharmacophore. The C-2 and C-22 hydroxyls are identified as hydrogen-bond acceptor sites which enhance activity. A hydrophobic site near C-12 is consistent with increasing activity. The side-chain substituents at C-17 are predicted to adopt semiextended "active" conformations which could fit into a cylinder-shaped binding pocket lined largely with nonpolar residues for enhanced activity. A test set of 20 ecdysteroids was used to evaluate the QSAR models. Two 4D-QSAR models for one alignment were identified to be superior to the others based on having the smallest average residuals of prediction for the prediction set (0.69 and 1.13 -log[EC(50)] units). The correlation coefficients of the optimum 4D-QSAR models (R(2) = 0.87 and 0.88) are nearly the same as those of the best CoMFA model (R(2) = 0.92) determined for the same training set. However, the cross-validation correlation coefficient of the CoMFA model is less significant (Q(2) = 0.59) than those of the 4D-QSAR models (Q(2) = 0.80 and 0.80).

Abstract
BACKGROUND Interleukin 10 (IL-10) is a homodimeric cytokine that shows considerable clinical promise. Adeno-associated virus (AAV) vectors appear increasingly useful for in vivo gene-transfer applications. METHODS A recombinant AAV type 2 vector encoding human IL-10 (rAAVhIL10) was constructed by using an adenoviral-free, three-plasmid co-transfection. Cytokine production was measured by using an enzyme-linked immunosorbent assay. Endotoxic shock was induced by lipopolysaccharide (LPS) injection. RESULTS As media from rAAVhIL10-infected COS cells caused a dose-dependent blockade of IL-12 secretion from spleen cells of IL-10 knockout (KO) mice challenged with Brucella abortus, it was clear that vector-derived hIL-10 was biologically active in vitro. Intravenous or intramuscular administration of relatively modest levels of rAAVhIL10 (10(10) genomes) to IL-10 KO mice resulted in hIL-10 secretion into the bloodstream, which, at 8 weeks, gave median serum levels of 0.9 and 0.45 pg/ml, respectively. Acute endotoxic shock led to a 33% mortality rate, and severe morbidity, in control IL-10 KO mice, whereas no mortality and little morbidity were seen in IL-10 KO mice given rAAVhIL10 7 weeks earlier. CONCLUSIONS The findings demonstrate that a modest dose of rAAVhIL10 administered in vivo provides long-term protection against LPS-induced endotoxic shock in a murine model. Thus, this vector may be useful for clinical applications requiring sustained IL-10 expression, for example in the treatment of several autoimmune diseases.

Abstract
Autoantigen-specific T cells have tissue-specific homing properties, suggesting that these cells may be ideal vehicles for the local delivery of immunoregulatory molecules. We tested this hypothesis by using type II collagen-specific (CII-specific) CD4(+) T hybridomas or primary CD4(+) T cells after gene transfer, as vehicles to deliver an immunoregulatory protein for the treatment of collagen-induced arthritis (CIA), a mouse model of rheumatoid arthritis (RA). CII-specific T cells or hybridomas were transduced using retroviral vectors to constitutively express the IL-12 antagonist, IL-12 p40. Transfer of engineered CD4(+) T cells after immunization significantly inhibited the development of CIA, while cells transduced with vector control had no effect. The beneficial effect on CIA of IL-12 p40-transduced T cells required TCR specificity against CII, since transfer of T cells specific for another antigen producing equivalent amounts of IL-12 p40 had no effect. In vivo cell detection using bioluminescent labels and RT-PCR showed that transferred CII-reactive T-cell hybridomas accumulated in inflamed joints in mice with CIA. These results indicate that the local delivery of IL-12 p40 by T cells inhibited CIA by suppressing autoimmune responses at the site of inflammation. Modifying antigen-specific T cells by retroviral transduction for local expression of immunoregulatory proteins thus offers a promising strategy for treating RA.
