This study describes a new mite species from marmots in a city park in Washington, noting that infested marmots displayed significant hair loss and tissue abnormalities.

This study found that lanugo hair appears earlier on the posterior wall of the trunk than on the anterior wall in human fetuses, with a nearly two-week difference in development time.

In this case report, treatment with ivermectin, antihistamines, vitamin B complex, and sulfur soap reduced skin lesions and itching in a 5-month-old dog diagnosed with demodecosis after 14 days.

This study reveals that β-catenin and retinoic acid are key regulators in the gene networks controlling the fate of skin appendages, such as scales and feathers.

Ets2 gene is crucial for placental development in mice.

In this study, researchers examined the histological structure of wild boar skin from three anatomical regions and found it comprises three main layers: epidermis, dermis, and hypodermis, containing various cell types and structures such as hair follicles, sebaceous glands, and fat cells.

In this experimental study, the researchers observed that Platycladus orientalis leaf extract promoted hair growth by enhancing dermal papilla cell proliferation and increasing growth factor expression, particularly through ACK1 activation and modulation of Wnt/β-catenin signaling pathways in cultured human cells and a 12-week topical application.

In this case report, a 2-month-old Chippiparai pup in Puducherry, India, successfully received treatment for concurrent scabies and dermatophytosis using ivermectin, a topical acaricide solution, a dewormer, and an herbal immunostimulant, with no signs of toxicity.

This study suggests that egfl6 expression in the pharyngeal pouches is not essential for craniofacial development in zebrafish.

This study found that nestin-expressing progenitor cells, capable of becoming ORS keratinocytes, are present in both developing and adult mouse hair follicles.

In this study, Msx2-deficient mice showed progressive hair loss due to shortened anagen phase and prolonged catagen and telogen phases, resulting in cyclic alopecia with structurally abnormal hair shafts.

This study observed that the development of the pars intermedia in long-tailed macaques is closely associated with changes in skin pigmentation during pre- and postnatal periods through melanocyte-stimulating hormone and ACTH activity.

This study found that keratin-associated proteins related to metallothionein and occludin appear in various animals, suggesting they may have roles beyond hair characteristics and were later adapted for hair production.

In this study, researchers identified CENPV as a new CYLD interacting partner that localizes to primary cilia and regulates acetylated tubulin levels, offering insights into the pathogenesis of skin appendage tumors.

In this study, researchers explored the heterogeneity of pigment cells in the human scalp anagen hair follicle bulb and discovered unexpected subpopulations of melanocytes, including immature SOX10-negative cells, highlighting potential non-melanogenic roles or transitional migratory functions that require further investigation.

Mouse embryos can develop in chick embryos, but they grow smaller with some organ issues.

This report describes a Sapajus nigritus investigated for multiparasitism after rescue from illegal home possession, highlighting public health and biodiversity conservation concerns related to human-primate proximity.

This study suggests that distinct chromatin topologies allow different lineage-specific enhancers to regulate Hoxd genes in mouse vibrissae and chicken feather primordia, while conserved regulatory elements maintain transcriptional robustness in the embryonic trunk across species.

This case report describes a dog suffering from dermatophytosis, a zoonotic fungal infection common in warm and humid climates, with alopecia noted in the neck region and the tip of the ear.

This study found that osteopontin mRNA is abundantly expressed in dermal papilla cells during the catagen phase of hair growth in rats, suggesting a role in this phase.

This article proposes an updated naming system for keratin-associated proteins and genes, aiming to improve data storage and retrieval by including species information and genetic variation.

This study found that trichostasis spinulosa was present in some seborrheic keratoses, indicating they may partly originate from hair follicle cells.

In this study, transiently activating the sonic hedgehog signaling pathway in chickens transformed reticulate scales on the feet into feathers comparable to body feathers, without ongoing treatment, suggesting this pathway affects the diversity of bird skin appendages.

This study found that ATP synthases and the mitochondrial gene COX2 play a key role in determining the size of skin appendages in hedgehogs and mice by influencing energy metabolism and cell proliferation.

This report describes a case study of a 23-year-old female exhibiting multiple trichodiscomas, a type of benign tumor of the hair follicular discs common in familial cases and potentially linked to Birt-Hogg-Dube syndrome, though genetic testing was not performed due to financial constraints.

This study reports five cases of congenital triangular alopecia featuring a central island of short terminal hair, with the cause remaining unknown.

This study found that Lymphotoxin-beta primarily influences periderm differentiation, impacting epidermal and hair follicle differentiation at later stages.

This study describes the successful management of Andean bear alopecia syndrome in three female bears using oclacitinib, leading to rapid pruritus resolution and fur regrowth without adverse effects.
