Conformational dynamics in interleukin 17A and 17F functional complexes is a key determinant of receptor A affinity and specificity.
Cytokine. 2021 Jun , 142:155476.

The proinflammatory cytokines IL-17A and IL-17F have been identified as key drivers of a range of human inflammatory diseases, such as psoriasis, which has led to several therapeutic antibodies targeted at IL-17A. The two cytokines have been shown to tightly associate as functional homo and hetero dimers, which induce signalling via the formation of a cell surface signalling complex with a single copy of both IL-17RA and IL-17RC. Striking differences in affinity have been observed for (...)

Protective Effects of Polyvinylpyrrolidone-Wrapped Fullerene Against Nitric Oxide/Peroxynitrite-Induced Cellular Injury in Human Skin Keratinocytes.
J Nanosci Nanotechnol. 2021 Sep 01, 21, (9):4579-4585.

Excess ultraviolet (UV) exposure accelerates skin inflammation, melanogenesis, wrinkle formation, photoaging, and carcinogenesis through oxidative stress and deoxyribonucleic acid damage. These deleterious effects to skin are closely associated with UV-induced reactive oxygen species (ROS) and reactive nitrogen species (RNS) produced via nitric oxide (NO) generation. RNS are known to be responsible for various skin disorders, such as erythema, melanin production, reduced barrier function, (...)

Catalpol ameliorates psoriasis-like phenotypes via SIRT1 mediated suppression of NF-κB and MAPKs signaling pathways.
Bioengineered. 2021 Dec , 12, (1):183-195.

Psoriasis is a chronic inflammatory skin disease that affects approximately 2% of worldwide population, and causing long-term troubles to the patients. Therefore, it is urgent to develop safe and effective therapeutic drugs. Catalpol is a natural iridoid glucoside, that has several remarkable pharmacological effects, however, whether catalpol can alleviated psoriasis has not been explored. The goal of the present work is to study the role of catalpol in psoriasis in vivo and in vitro. (...)

Viral metagenomic identification of a novel anellovirus in blood sample of a child with atopic dermatitis.
J Med Virol. 2021 Jun , 93, (6):4038-4041.

Here, using viral metagenomics, a novel anellovirus with strain name HuAV-zj-ad1 was detected in blood sample from a child with atopic dermatitis. The complete genome sequence of HuAV-zj-ad1 was determined and fully characterized. The circular genome of HuAV-zj-ad1 is 2841 nt in length and includes four polyprotein ORFs. Phylogenetic analysis and pairwise sequence comparisons based on the amino acid sequences of ORF1, ORF2, ORF3, ORF4 indicated that HuAV-zj-ad1 belonged to a novel species (...)

Dupilumab therapy for patients with refractory eosinophilic otitis media associated with bronchial asthma.
Auris Nasus Larynx. 2021 Jun , 48, (3):353-360.

Eosinophilic otitis media (EOM) is an intractable otitis media mostly associated with bronchial asthma. Dupilumab, an anti-interleukin (IL)-4 receptor (R)α, is effective and has been approved for use in patients with moderate to severe bronchial asthma, atopic dermatitis and chronic rhinosinusitis with nasal polyposis, whose diseases are not controlled by previous treatments including other molecular targeted drugs. We aimed to assess efficacy of dupilumab in three EOM patients with (...)

Cavalcante FS et al.
Methicillin-resistant from infected skin lesions present several virulence genes and are associated with the CC30 in Brazilian children with atopic dermatitis.
Virulence. 2021 12 , 12, (1):260-269.

Atopic dermatitis (AD) is a chronic inflammatory skin disease and colonization by may affect up to 100% of these patients. Virulent and resistant isolates can worsen AD patient clinical condition and jeopardize the treatment. We aimed to detect virulence genes and to evaluate the biofilm production of isolates from infected skin lesions of children with AD. Methicillin resistance was detected by phenotypic and molecular tests and the virulence genes were detected by PCR. Biofilm formation (...)
