Abstract
Autoimmune encephalitis (AE) is increasingly recognized as a cause of brain disorders that greatly benefit from immunotherapy. Starting treatment quickly and increasing the use of immunotherapy can lead to better results for AE patients. Currently, there are standardized treatment guidelines for treating AE. First-line therapy includes intravenous corticosteroids, plasma exchange, and intravenous immunoglobulin. Second-line therapy involves rituximab, cyclophosphamide, mycophenolate mofetil, and azathioprine. Third-line therapy uses agents that deplete plasma cells (bortezomib, daratumumab, and obinutuzumab), drugs that modulate cytokines (tocilizumab, anakinra, tofacitinib, and interleukin-2), and treatments that target intrathecal immune cells (intrathecal methotrexate). This review aims to summarize the immunotherapeutic strategies available for treating AE and provide an update on refractory AE.

Abstract
Dental abnormalities are often detected in childhood and are reported to occur with high prevalence in patients who have undergone cancer treatment or chemotherapy. We performed a literature search of PubMed from 2004 to 2024 using the terms "dental anomaly" and "panoramic examination", and 298 potentially relevant articles were found. Thirty-one articles about dental abnormalities matched the eligibility criteria and were extracted for this review. Although the prevalence of tooth agenesis and microdontia in the general population was reported to be approximately 10% and 3%, respectively, the prevalence in patients who had undergone cancer treatment or chemotherapy was higher in all surveys, suggesting that the treatment is related to the occurrence of dental abnormalities. It is important to continue long-term follow-up with patients not only during treatment but also after the completion of treatment. Dental professionals should provide information about dental abnormalities to patients, their guardians, and medical professionals, which may lead to improvement in the quality of life of patients.

Abstract
The newly constituted National Multiple Sclerosis (MS) Society (NMSS)of the United Arab Emirates (UAE), set up a scientific committee to create a MS disease modifying treatment (DMT) guideline for UAE. The committee considered several unique features of the MS community in UAE including large number of expatriate population, wide variations in health insurance coverage, physician and patient preferences for DMT. The overall goal of the treatment guideline is to facilitate the most appropriate DMT to the widest number of patients. To this end it has adapted recommendations from various health systems and regulatory authorities into a pragmatic amalgamation of best practices from across the world. Importantly where data is unavailable or controversial, a common sense approach is taken rather than leave physicians and patients in limbo. The committee classifies MS into subcategories and suggests appropriate treatment choices. It recommends treatment of RIS and CIS with poor prognostic factors. It largely equates the efficacy and safety of DMT with similar mechanisms of action or drug classes e.g. ocrelizumab is similar to rituximab. It allows early switching of treatment for unambiguous disease activity and those with progression independent of relapses. Autologous hematopoietic stem cell transplantation can be offered to patients who fail one high efficacy DMT. Pragmatic guidance on switching and stopping DMT, DMT choices in pregnancy, lactation and pediatric MS have been included. It is expected that these guidelines will be updated periodically as new data becomes available.

Abstract
El objetivo de este estudio fue evaluar el posible efecto terapéutico del propóleo sobre la peroxidación lipídica testicular inducida por ciclofosfamida (CP) y sobre los cambios asociados en los parámetros espermatológicos en los espermatozoides epididimarios y la estructura histopatológica de los testículos de rata. Las ratas se separaron aleatoriamente en 4 grupos con 7 ratas en cada grupo. Se formaron grupos como; 1.er grupo: grupo control (ratas no tratadas), 2.º grupo: grupo tratado con propóleo, 3.er grupo: grupo tratado con CP y 4.º grupo: grupo tratado con CP+propóleo. Se administró propóleo a las ratas en una dosis de 200 mg·kg bw -1 mediante alimentación forzada durante 7 días (d). Se administró CP a las ratas en una dosis única de 150 mg·kg pc -1 por vía intraperitoneal. La administración de propóleo se inició 2 días antes de la administración de CP y continuó durante 7 días. Niveles de malondialdehído (MDA) y glutatión reducido (GSH), actividades de catalasa (CAT), glutatión peroxidasa (GSH-Px), glutatión S-transferasa (GST) y superóxido dismutasa (SOD), parámetros espermatológicos, peso de los órganos reproductivos. y se determinó la estructura histopatológica. En comparación con el grupo de control, los niveles de MDA y las actividades de SOD aumentaron significativamente; Si bien las actividades de CAT y GST disminuyeron, no se encontraron cambios en los niveles de GSH ni en las actividades de GSH-Px en el grupo CP. En el grupo tratado con CP, hubo una disminución en la motilidad de los espermatozoides del epidídimo, la densidad de los espermatozoides en los espermatozoides del epidídimo y el peso de los testículos, la próstata, el epidídimo y la vesícula seminal; mientras que hubo un aumento en la proporción de espermatozoides anormales en comparación con el grupo de control en los espermatozoides epididimarios. El propóleo normalizó los parámetros bioquímicos y espermatológicos en los espermatozoides epididimarios. El examen histopatológico del tejido testicular mostró que los cambios histopatológicos más significativos, como restos celulares, invaginación y degeneración, ocurrieron en el grupo CP. En la patogénesis de la toxicidad testicular inducida por la PC puede desempeñar un papel el deterioro del equilibrio oxidante-antioxidante y el propóleo puede reducir los efectos secundarios graves de las alteraciones inducidas por la PC.

Abstract
While efforts to identify microglial subtypes have recently accelerated, the relation of transcriptomically defined states to function has been largely limited to in silico annotations. Here, we characterize a set of pharmacological compounds that have been proposed to polarize human microglia towards two distinct states - one enriched for AD and MS genes and another characterized by increased expression of antigen presentation genes. Using different model systems including HMC3 cells, iPSC-derived microglia and cerebral organoids, we characterize the effect of these compounds in mimicking human microglial subtypes in vitro. We show that the Topoisomerase I inhibitor Camptothecin induces a CD74high/MHChigh microglial subtype which is specialized in amyloid beta phagocytosis. Camptothecin suppressed amyloid toxicity and restored microglia back to their homeostatic state in a zebrafish amyloid model. Our work provides avenues to recapitulate human microglial subtypes in vitro, enabling functional characterization and providing a foundation for modulating human microglia in vivo.

Abstract
Multiple sclerosis (MS) is the most prevalent chronic autoimmune inflammatory- demyelinating disorder of the central nervous system (CNS). It usually begins in young adulthood, mainly between the second and fourth decades of life. Usually, the clinical course is characterized by the involvement of multiple CNS functional systems and by different, often overlapping phenotypes. In the last decades, remarkable results have been achieved in the treatment of MS, particularly in the relapsing- remitting (RRMS) form, thus improving the long-term outcome for many patients. As deeper knowledge of MS pathogenesis and respective molecular targets keeps growing, nowadays, several lines of disease-modifying treatments (DMT) are available, an impressive change compared to the relative poverty of options available in the past. Current MS management by DMTs is aimed at reducing relapse frequency, ameliorating symptoms, and preventing clinical disability and progression. Notwithstanding the relevant increase in pharmacological options for the management of RRMS, research is now increasingly pointing to identify new molecules with high efficacy, particularly in progressive forms. Hence, future efforts should be concentrated on achieving a more extensive, if not exhaustive, understanding of the pathogenetic mechanisms underlying this phase of the disease in order to characterize novel molecules for therapeutic intervention. The purpose of this review is to provide a compact overview of the numerous currently approved treatments and future innovative approaches, including neuroprotective treatments as anti-LINGO-1 monoclonal antibody and cell therapies, for effective and safe management of MS, potentially leading to a cure for this disease.

Abstract
Cyclophosphamide (CP) is mainly used to treat autoimmune diseases and cancer; however, it damages normal immune cells. Therefore, the effects of chemotherapy on CP are limited. Notably, green tea has been reported to effectively modulate immune function. Here, given the pharmacological properties of green tea, we evaluated the ability of green tea extract (GTE) to restore immunity suppressed by CP in vivo and to activate macrophages in vitro. GTE significantly improved the suppressed immune function, including spleen index and proliferation of spleen T lymphocytes, as revealed by histopathological examination and flow cytometry analysis. Moreover, GTE effectively activated RAW 264.7, as represented by the induction of nitric oxide, reactive oxygen species, and cytokine levels. GTE also increased the phosphorylation of mitogen-activated protein kinases (MAPKs) and nuclear factor kappa B in RAW 264.7 cells. In conclusion, GTE ameliorated CP-induced immunosuppression in mice and stimulated immune activity in RAW 264.7 cells, possibly by activating the MAPK signaling pathway. These findings suggest that GTE has the potential to be used as a supplementary agent in chemotherapy for CP.

Abstract
BACKGROUND Clinical observation has revealed that multiple sclerosis (MS) and autoimmune thyroid disease (AITD) are strongly correlated. The aim of this study was to explore the shared molecular causes of MS and AITD, and to conduct drug rearrangement on this basis, search for comorbidity drugs and feasible drugs for mutual reference between the two diseases. METHODS Based on genome-wide association study (GWAS) data and transcriptome data, susceptibility genes and differentially expressed genes related to MS and AITD were identified by bioinformatics analysis. Pathway enrichment, gene ontology (GO), protein-protein interaction analysis, and gene-pathway network analysis of the above genes were performed to identify a common target pool, including common genes, common hub genes, and common pathways, and to explore the specific pathogenesis of the two diseases, respectively. Drugs that target the common pathways/genes were identified through the Comparative Toxicogenomics Database (CTD), DrugBank database, and Drug-Gene Interaction (DGI) Database. Common hub genes were compared with the target genes of drugs approved for treating MS/AITD and drugs under investigation identified by DrugBank and ClinicalTrials, respectively. RESULTS We identified a pool of shared targets containing genes and pathways, including 46 common genetic susceptibility pathways and 9 common differentially expressed pathways, including JAK-STAT signaling pathway, Th17 cell differentiation, Th1 and Th2 cell differentiation, PD-L1 expression and PD-1 checkpoint pathway in cancer, etc. In addition, a total of 29 hub genes, including TYK2, JAK1, STAT3, IL2RA, HLA-DRB1, and TLR3, were identified. Drugs approved for treating MS or AITD, such as methylprednisolone, cyclophosphamide, glatiramer, natalizumab, and methimazole, can target the shared genes and pathways, among which methylprednisolone and cyclophosphamide have been shown to be beneficial for the treatment of the two diseases, indicating that these drugs have the potential to become a priority in the treatment of comorbidities. Moreover, drugs targeting multiple common genes and pathways, including tacrolimus, deucravacitinib, and nivolumab, were identified as potential drugs for the treatment of MS, AITD, and their comorbidities. CONCLUSION We observed that T-cell activation-related genes and pathways play a major role in the pathogenesis of both MS and AITD, which may be the molecular basis of the comorbidity. Moreover, we identified a variety of drugs which may be used as priority or potential treatments for comorbidities.

Abstract
Multiple sclerosis (MS) is a chronic, autoimmune condition that primarily affects the myelin sheath covering the neurons of the central nervous system, including those of the brain and spinal cord. Although the etiology is not completely understood, various factors, such as genetic infections and environmental background, play a role in the pathogenesis. Repeated active episodes of MS characterized with marked inflammation results in the scarring of particular nerve segments, and eventually results in functional impairment over a period of time. Based on the clinical course of the disease, four clinical types of MS have been identified, with the relapsing-remitting type being the commonest. MS is known to occur more commonly in females in the age group of 20-40 years. Dysarthria, fatigue, muscle spasm, and numbness are the common presenting symptoms of MS. Diagnosis is generally achieved with MRI brain scans, showing demyelination plaques and lumbar puncture. Treatment of MS's acute phase includes high doses of corticosteroids; whereas preventive treatment of MS includes the prescription of immunosuppressive therapy, including biologics. A large group of MS patients present with oral manifestations, including dysphagia, dysarthria, temporomandibular joint (TMJ) disturbances, facial palsy, and chronic periodontal diseases. Other typical oral manifestations seen in MS patients include trigeminal neuralgia, paresthesia, or orofacial pain. Dental treatment and following drug prescription needs to be tailored to each patient, as there is a possibility of drug interactions. This paper presents a comprehensive, updated review of MS, with emphasis on oral manifestations and dental considerations. Additionally, it presents a case of a 40-year-old female diagnosed with MS that was presented to a dental hospital. The report discusses the oral manifestations and dental management.

Abstract
Cyclophosphamide (CYC) may be an effective treatment in patients who fail first line therapy for severe central nervous system (CNS) inflammatory disorders including CNS vasculitis, neuromyelitis optica, autoimmune encephalitis, tumefactive and aggressive multiple sclerosis (MS). We performed a retrospective analysis of 46 patients treated with CYC after failing first line therapy for severe CNS inflammatory conditions. Primary outcomes included modified Rankin Scale (mRS) for patients classified into a non-MS group, Expanded Disability Status Score (EDSS) for MS patients, and Targeted Neurological Deficit score (TND) for all patients. Secondary outcome included neuroimaging studies following CYC treatment. By the second follow up period (average of 7 months) mRS in the non-MS group improved from 3.7 to 2.2 and EDSS in the MS group improved from 5.6 to 3.8. Average TND score at 7 months was 2.8 (mild-marked improvement). At first follow up (average 5.6 months), 76.2% (32/42) patients had either stable or improving imaging, and 83.3% (30/36) patients had stable or improving imaging at second follow up (average 13.6 months). Adverse events were reported by 31.9% of patients with most common being nausea and vomiting, headache, alopecia, and hyponatremia. Treatment with CYC can result in disease stabilization of severe CNS inflammatory diseases and is generally well tolerated.

Abstract
The review is devoted to the development and study of the drug Leukovir® (cladribine+ ribavirin) and its use in the treatment of relapsing-remitting and secondary progressive forms of multiple sclerosis, a chronic neurodegenerative disease aiming the risk reduction of relapse and progression of a disability. In clinical trials Leukovir® has proved to be efficient by up to 56 weeks for the treatment of relapsing-remitting and secondary progressive forms of multiple sclerosis. The drug is registered in the Republic of Belarus. The efficacy, safety and tolerability profile of the drug Leukovir® suggests that it is well suited for disease-modifying therapy of multiple sclerosis. Patients require four 35-day courses of treatment, each consisting of seven days of treatment followed by a break of 28 days. The use of Leukovir® has contributed to the suppression of inflammatory process activity according to MRI data and stabilization of the clinical condition. It has reduced the number of relapses in patients with relapsing-remitting and secondary-progressive forms of multiple sclerosis.

American ginseng with different processing methods ameliorate immunosuppression induced by cyclophosphamide in mice via the MAPK signaling pathways. Front Immunol 2023; 14:1085456.

Abstract
This study aimed to clarify the effects of two processed forms of American ginseng (Panax quinquefolius L.) on immunosuppression caused by cyclophosphamide (CTX) in mice. In the CTX-induced immunosuppressive model, mice were given either steamed American ginseng (American ginseng red, AGR) or raw American ginseng (American ginseng soft branch, AGS) by intragastric administration. Serum and spleen tissues were collected, and the pathological changes in mice spleens were observed by conventional HE staining. The expression levels of cytokines were detected by ELISA, and the apoptosis of splenic cells was determined by western blotting. The results showed that AGR and AGS could relieve CTX-induced immunosuppression through the enhanced immune organ index, improved cell-mediated immune response, increased serum levels of cytokines (TNF-α, IFN-γ, and IL-2) and immunoglobulins (IgG, IgA, and IgM), as well as macrophage activities including carbon clearance and phagocytic index. AGR and AGS downregulated the expression of BAX and elevated the expression of Bcl-2, p-P38, p-JNK, and p-ERK in the spleens of CTX-injected animals. Compared to AGS, AGR significantly improved the number of CD4+CD8-T lymphocytes, the spleen index, and serum levels of IgA, IgG, TNF-α, and IFN-γ. The expression of the ERK/MAPK pathway was markedly increased. These findings support the hypothesis that AGR and AGS are effective immunomodulatory agents capable of preventing immune system hypofunction. Future research may investigate the exact mechanism to rule out any unforeseen effects of AGR and AGS.

Abstract
The study was designed to explore the improvement effect of CSPCM (compound small peptide of Chinese medicine) on intestinal immunity and microflora through the treatment of different doses of CSPCM. A total of 100 male Kunming mice were weighed and divided into five groups, namely, group A (control group), group B (model group), group C (0.1 g/kg·bw CSPCM), group D (0.2 g/kg·bw CSPCM), and group E (0.4 g/kg·bw CSPCM). The use of CTX (cyclophosphamide) caused a series of negative effects: the secretion of IL-2, IL-22, TNF-α, sIgA, length of the villi, and the area of Pey's node were significantly reduced (P < 0.05); the depth of crypt and the percent of CD3+ and CD4+ cells were significantly increased (P < 0.05); the cecal flora taxa decreased; the abundance of Firmicutes and Lactobacillus increased; and the abundance of Bacteroidetes, Deferribacteres, Proteobacteria, Mucispirillum, Bacteroides, and Flexisprra decreased. The addition of CSPCM improved the secretion of cytokines and the development of intestinal villi, crypts, and Pey's node. The number of CD3+ and CD4+ cells in groups C, D, and E was significantly higher than that in group B (P < 0.05). Compared with group B, the abundance of Firmicutes in groups C, D, and E was decreased, and the Bacteroidetes, Deferribacteres, and Proteobacteria increased. The abundance of Lactobacillus decreased, while that of Mucispirillum, Bacteroides, and Flexisprra increased. It is concluded that cyclophosphamide is extremely destructive to the intestinal area and has a great negative impact on the development of the small intestine, the intestinal immune system, and the intestinal flora. The CSPCM can improve the negative effects of CTX.

Abstract
Multiple sclerosis (MS) is a chronic and complex neurodegenerative disease, distinguished by the presence of lesions in the central nervous system (CNS) due to exacerbated immunological responses that inflict oligodendrocytes and the myelin sheath of axons. In recent years, studies have focused on targeted therapeutics for MS that emphasize the role of G protein-coupled receptors (GPCRs), specifically cannabinoids receptors. Clinical studies have suggested the therapeutic potential of cannabinoids derived from Cannabis sativa in relieving pain, tremors and spasticity. Cannabinoids also appear to prevent exaggerated immune responses in CNS due to compromised blood-brain barrier. Both, endocannabinoid system (ECS) modulators and cannabinoid ligands actively promote oligodendrocyte survival by regulating signaling, migration and myelination of nerve cells. The cannabinoid receptors 1 (CB1) and 2 (CB2) of ECS are the main ones in focus for therapeutic intervention of MS. Various CB1/CB2 receptors agonists have been experimentally studied which showed anti-inflammatory properties and are considered to be effective as potential therapeutics for MS. In this review, we focused on the exacerbated immune attack on nerve cells and the role of the cannabinoids and its interaction with the ECS in CNS during MS pathology.

Abstract
Many groundbreaking advances have occurred in the field of multiple sclerosis since this series last reviewed the disorder in 2014. The U.S. Food and Drug Administration has approved 7 new medications for relapsing-remitting multiple sclerosis and approved the first medication for primary progressive multiple sclerosis. The McDonald criteria for diagnosing multiple sclerosis were updated in 2017. New blood tests can now differentiate patients with multiple sclerosis from those with neuromyelitis optica spectrum disorder, and 3 new medications have been approved specifically for the latter disorder. Also, new medications for treating the symptoms of multiple sclerosis have been introduced.
