Combination of Adult Mesenchymal Stem Cell Therapy and Immunomodulation with Dimethyl Fumarate Following Spinal Cord Ventral Root Repair.

Spinal cord injury results in significant motor and sensory loss. In the experimental ventral root avulsion (VRA) model, the ventral (motor) roots are disconnected from the spinal cord surface, disrupting contact between spinal motoneurons and muscle fibers. Axotomized motoneurons typically degenerate within two to three weeks after avulsion, the situation being exacerbated by an increased glial response and chronic inflammation.

The impact of ERP29 on the progression of pharyngeal squamous cell carcinoma.

ERP29 gene encodes a chaperone protein critical for protein folding and secretion. Previous study linked ERP29 inhibition to an elevated risk of pharynx squamous cell carcinoma (PSCC) and reduced patients' survival. However, ERP29 role in PSCC progression remains unknown.

Corrigendum: Neuroprotection by upregulation of the major histocompatibility complex class I (MHC I) in SOD1 mice.

[This corrects the article DOI: 10.3389/fncel.2023.

Oligodendrocyte precursor cell-derived exosomes combined with cell therapy promote clinical recovery by immunomodulation and gliosis attenuation.

Multiple sclerosis is a chronic inflammatory disease of the central nervous system characterized by autoimmune destruction of the myelin sheath, leading to irreversible and progressive functional deficits in patients. Pre-clinical studies involving the use of neural stem cells (NSCs) have already demonstrated their potential in neuronal regeneration and remyelination. However, the exclusive application of cell therapy has not proved sufficient to achieve satisfactory therapeutic levels.

Attenuated mutants of Typhimurium mediate melanoma regression via an immune response.

The lack of effective treatment options for an increasing number of cancer cases highlights the need for new anticancer therapeutic strategies. Immunotherapy mediated by Typhimurium is a promising anticancer treatment. Candidate strains for anticancer therapy must be attenuated while retaining their antitumor activity.

Neuroprotection by upregulation of the major histocompatibility complex class I (MHC I) in SOD1 mice.

Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease that progressively affects motoneurons, causing muscle atrophy and evolving to death. Astrocytes inhibit the expression of MHC-I by neurons, contributing to a degenerative outcome. The present study verified the influence of interferon β (IFN β) treatment, a proinflammatory cytokine that upregulates MHC-I expression, in SOD1 transgenic mice.

Interferon-beta induces major histocompatibility complex of class I (MHC-I) expression and a proinflammatory phenotype in cultivated human astrocytes.

Major histocompatibility complex class I (MHC-I) has been implicated in several types of neuroplasticity phenomena. Interferon beta-1b (IFN-β) increases MHC-I expression by motoneurons after sciatic nerve crush in mice, improving axonal growth and functional recovery. Additionally, IFN-β induces glial hypertrophy associated with upregulation of glial fibrillary acidic protein (GFAP) and MHC-I in murine astrocytes in vitro.

Silver Nimesulide Complex in Bacterial Cellulose Membranes as an Innovative Therapeutic Method for Topical Treatment of Skin Squamous Cell Carcinoma.

Oxidative stress and inflammation act on skin squamous cell carcinoma (SSCC) development and progression. Curative therapy for SSCC patients is mainly based on surgical resection, which can cause various sequelae. Silver ions have in vitro activities over tumor cells, while nimesulide has antioxidant and anti-inflammatory activities.

Intronic variants of MITF (rs7623610) and CREB1 (rs10932201) genes may enhance splicing efficiency in human melanoma cell line.

We previously reported that intronic single nucleotide variations (SNVs) in MITF (c.938-325G>A, rs7623610) and CREB1 (c.303+373G>A, rs10932201) genes were associated with risk, aggressiveness, and prognosis of cutaneous melanoma (CM).

Association between IL-27 and Tr1 cells in severe form of paracoccidioidomycosis.

Interleukin-27, a cytokine of the IL-12 family, is secreted by antigen-presenting cells such as macrophages and dendritic cells (DCs). Recent studies suggest an anti-inflammatory role for IL-27 by inducing IL-10 producing Tr1 cells capable of inhibiting Th1 and Th17 type responses. Our study aimed to investigate the involvement of IL-27 and Tr1 cells in the immunomodulation of paracoccidioidomycosis (PCM), the most prevalent systemic mycosis in Brazil.
