Macrophages and autophagy: partners in crime

The FEBS Journal, EarlyView.
Autophagy is a key regulator of macrophage function, influencing critical processes like polarization, cytokine secretion, and phagocytosis. Its impact on macrophage behavior varies across different tissues and disease contexts, where it can either promote protective responses or contribute to detrimental outcomes, depending on the physiological or ...

d‐amino acids: new functional insights

The FEBS Journal, EarlyView.
This review explores recent advances in understanding d‐amino acids (d‐AAs) and their pivotal roles across organisms, from plants to humans. d‐AAs have been implicated in key physiological processes, including cancer, inflammation, immune regulation, kidney disease, diabetes, and nervous system function.

CD207+ CD103+ dermal dendritic cells cross-present keratinocyte-derived antigens irrespective of the presence of Langerhans cells

Journal of Experimental Medicine, 2010
Recent studies have challenged the view that Langerhans cells (LCs) constitute the exclusive antigen-presenting cells of the skin and suggest that the dermal dendritic cell (DDC) network is exceedingly complex.

Morphological, immunohistochemical and molecular analysis of follicular dendritic cell sarcomas: L1CAM as a new diagnostic marker

Histopathology, EarlyView.
Pathohistological analysis of FDCS revealed a morphological spectrum and led to the identification of the adhesion molecule L1CAM as a novel diagnostic immunomarker for FDCS. Sequencing identified NFKBIA as the most frequently altered gene, of note, exclusively in cases with a predominant epithelioid cytomorphology.

Rho-associated kinase regulates Langerhans cell morphology and responsiveness to tissue damage

Cell Reports
Summary: Skin damage requires efficient immune cell responses to restore organ function. Epidermal-resident immune cells known as Langerhans cells use dendritic protrusions to surveil the skin microenvironment, which contains keratinocytes and peripheral

Histiocitose de células de Langerhans: doença de Letterer-Siwe - importância do diagnóstico dermatológico em dois casos Langerhans cell histiocytosis: Letterer-Siwe disease - the importance of dermatological diagnosis in two cases

Anais Brasileiros de Dermatologia, 2009
A histiocitose de células de Langerhans é proliferação clonal de células fenotipicamente semelhantes às células de Langerhans. Anteriormente denominada Letterer-Siwe, é a forma mais comum e mais grave dessa enfermidade, acometendo sobretudo crianças até ...

Darier disease: Current insights and challenges in pathogenesis and management

Journal of the European Academy of Dermatology and Venereology, Volume 39, Issue 5, Page 942-951, May 2025.
Darier disease (DD) is characterized by the following: Disrupted Ca2+ gradients, impaired desmosomes, impaired keratinocyte differentiation, type 17 inflammation, DC and LC ↓, Th17 cells ↑. DD treatment: First line: keratinocyte focused and/or anti‐inflammatory. Second line: experimental approaches like specific targeting of the inflammatory infiltrate.

Interactions of Human Dermal Dendritic Cells and Langerhans Cells Treated with Hyalomma Tick Saliva with Crimean-Congo Hemorrhagic Fever Virus

Viruses, 2018
Crimean-Congo hemorrhagic fever virus is one the most important and wide spread tick-borne viruses. Very little is known about the transmission from the tick and the early aspects of pathogenesis.

Topographical variations in the skin barrier and their role in disease pathogenesis

Journal of the European Academy of Dermatology and Venereology, EarlyView.
Unlike the gut, the skin appears uniform at first glance. However, histological and molecular biological research has revealed significant regional variations in the composition and function of its main barrier elements. In this review, we describe the topographical differences of four barrier elements in healthy skin: microbiome, chemical, physical ...
