Objective: A pathogenetic role of CD8+ T lymphocytes in radiographic axial spondyloarthritis (r-axSpA) and other spondyloarthritis (SpA) is sustained by genome-wide association studies (GWAS) and by the expansion of public T cell clonotypes in the target tissues. This study investigates the migration of CD8+ T cells, along with their phenotype and functions in patients with r-axSpA and psoriatic arthritis (PsA).
Methods: Peripheral blood CD8+ and CD4+ T cells were isolated from r-axSpA (n= 128), PsA (n= 60) and rheumatoid arthritis (RA, n= 74) patients and healthy donors (HD, n= 79).
The heart employs a specialized ribosome in its muscle cells to translate genetic information into proteins, a fundamental adaptation with an elusive physiological role. Its significance is underscored by the discovery of neonatal patients suffering from often fatal heart failure caused by rare compound heterozygous variants in RPL3L, a muscle-specific ribosomal protein that replaces the ubiquitous RPL3 in cardiac ribosomes. -linked heart failure represents the only known human disease arising from mutations in tissue-specific ribosomes, yet the underlying pathogenetic mechanisms remain poorly understood despite an increasing number of reported cases.

Pathogenic variants of cause Charcot-Marie-Tooth disease (CMT), an inherited neuropathy characterized by axonal degeneration. GDAP1, an atypical glutathione S-transferase, localizes to the outer mitochondrial membrane (OMM), regulating this organelle's dynamics, transport, and membrane contact sites (MCSs). It has been proposed that GDAP1 functions as a cellular redox sensor.

Alzheimer's disease is a complicated, multifaceted, neurodegenerative illness that places an increasing strain on healthcare systems. Due to increasing malfunction and death of nerve cells, the person suffering from Alzheimer's disease (AD) slowly and steadily loses their memories, cognitive functions and even their personality. Although medications may temporarily enhance memory, there are currently no permanent therapies that can halt or cure this irreversible neurodegenerative process.

Acne and acne sequelae can have an important impact on patients' quality of life, affecting interpersonal relationships and social functioning. Acne-induced scars (AIS) and acne-induced macular hyperpigmentation (AIH), in particular, are a major concern for patients with acne, as their management is challenging and often unsatisfactory. Retinoids are considered the mainstay of acne treatment because of their action on multiple pathogenetic factors, and there is increasing evidence that they can also improve AIS and AIH.
