This review discusses the role of the TCL1 transgenic mouse model in understanding chronic lymphocytic leukemia biology and highlights the importance of exploring new pathogenetic and therapeutic targets.

This study in SPF lambs found that primary and secondary orf virus infections trigger similar skin responses, but the primary infection caused a more severe and prolonged reaction.

This case report describes a rare coexistence of primary subcutaneous panniculitis-like T-cell lymphoma and lupus panniculitis in a 20-year-old Moroccan woman, highlighting the importance of repeated biopsies for accurate diagnosis in resistant cases.

This study found that dermatoscopy is useful for diagnosing and assessing primary cicatricial alopecias in Chinese patients, with alopecia mucinosa having a distinct feature of patulous follicular openings.

This research analyzed 72 primary scarring alopecia cases in a Barcelona hospital, finding that the majority involved women, with a lymphocytic infiltrate and subacute onset in many cases, leading to stable disease, while neutrophilic cases had more acute episodes.

In this study, cicatricial alopecias were classified by inflammatory cell type and the researchers highlighted that primary cicatricial alopecia's exact causes remain unknown, accounting for 6% of all hair diseases despite its unclear prevalence.

Lichen planopilaris is a rare, chronic condition causing hair loss, mainly in middle-aged women, and early treatment is important to prevent permanent baldness.

Enhancing regulatory T cells may help treat autoimmune diseases like alopecia areata.

Immunosuppressive therapy helps manage autoimmune diseases but carries risks like infection and potential for malignancy.

This study demonstrated that stress inhibited hair growth in mice, likely through substance P-dependent activation of immune cells, highlighting a brain-hair follicle connection.

This study reported that alopecia occurred in 2.5% of patients with mycosis fungoides or Sézary syndrome, with some cases resembling alopecia areata and others associated with specific skin lesions.

This review discusses the role of immune responses, especially Th1 cytokines, in alopecia areata pathogenesis and reports no new research findings.

This study conducted a meta-analysis of gene expression data from alopecia areata patients, identifying 5109 differentially expressed genes and highlighting enriched pathways like JAK-STAT signaling, providing insights into the disease's pathogenesis and potential treatment targets.

The study introduced an advanced skin model, ImmuSkin-MT, which effectively distinguished between different strengths of skin sensitizers by mimicking the interaction of immune cells in skin tissue.

This historical review discusses the ancient Egyptians' advanced wound-healing techniques, including the use of honey and moldy bread, and reports no new clinical results.

This article reviews the social and functional impact of eyebrow loss and highlights the limited treatment options compared to scalp alopecia, but reports no new clinical results.

This source describes a case of a 12-year-old male diagnosed with folliculotropic mycosis fungoides, presenting with an asymptomatic, erythematous plaque. Histology and immunohistochemistry confirmed FMF, which is typically rare in children and marked by follicular infiltration by CD4+ lymphocytes.

This case report describes an instance of alopecia and severe seborrhoeic dermatitis potentially linked to the immune response from starting combination antiretroviral therapy for acute retroviral syndrome.

This study found that topical application of Astragalus membranaceus extract induced hair regrowth and reduced immune response markers in mice with natural hair loss.

This study found that discoid lupus erythematous was the most common type of primary cicatricial alopecia, predominantly affecting middle-aged women.

This article discusses various treatments for primary cicatricial alopecia with a focus on early intervention to manage symptoms and improve hair density, but it reports no new clinical results.

This study observed that 2.5% of patients with mycosis fungoides or Szary syndrome experienced alopecia, predominantly within skin lesions, with scalp metastases from other cancers also potentially causing hair loss, highlighting the diagnostic value of trichoscopy in differentiating alopecia types.

This article reviews lichen planopilaris, a chronic scarring alopecia, and explores recent treatment developments, but it reports no new clinical results.

This study found that CD45RO+ cells, a subtype of T lymphocytes, were notably reduced in the ovarian follicles of women with PCOS, which may contribute to the condition's pathogenesis.

This review discusses the effects of valproic acid on immune cell activation and gene expression, potentially influencing infection outcomes and suggesting its promise for autoimmune and hypersensitivity condition management.

This review discusses the role and mechanisms of unconventional lymphocytes in promoting tissue repair and maintaining mucosal barrier integrity in the skin, gut, and lungs, but reports no new findings.

An 8-year-old girl developed a rare skin condition in a linear pattern on one side of her body after a lung infection, which improved with treatment.

This study found that dermal injection of M-CSF stimulated CD11b + myeloid cells can induce alopecia areata in mice by potentially activating B lymphocytes, offering insight into the disease's pathogenesis.

North American ginseng extract helped regrow hair in balding mice.

This review analyzed literature on primary cutaneous lymphomas involving the scalp, finding that scalp involvement in these cases often leads to non-scarring focal alopecia and may indicate more aggressive disease.
