Excited to see my image on the cover of @NatImmunol!
The scanning electron microscopy image shows lymph node ECM conduits (following removal of cells), which serve as a mechanosensation platform for stromal cells to coordinate organ growth. Read more: https://t.co/VA7V0rA62W

Hello everyone, excited to share our preprint: https://t.co/DoThdFBDLT

Everyday, cells like this crawl through your body to protect you. While we know that their front 🔴 and back 🔵 polarity programs work together, how exactly do these two processes communicate? Lets chat!

[Michael Riedl @mi_riedl]

Guess which of these movies are played forward and which backward? It's not that easy isn't it? We were similarly confused about this, so we started a project with our favourite toy system on entropy in macroscale active matter:

Cover image: depicts a shallow 3D reconstruction of the dermal-epidermal interphase of a human skin section showing the close interaction between #melanocytes and #keratinocytes in the #epidermis. The image was acquired on a dual-laser two-photon microscope, and label-free second-harmonic and third-harmonic imaging (SHG/THG) was used to capture fibrillar collagen (gray) and basal keratinocytes (purple), respectively. Other keratinocyte layers and melanocytes were stained with respective antibodies against Keratin-10 (red) and beta III Tubulin (cyan).

Fly-Over: Visualization of Melanocytes Lining the Hair Follicles and Epidermis The video showcases a 3D fly-over of immune-stained human skin, highlighting melanocytes (identified by tubulin 3 in white) that line the junction between the hair follicle and the epidermis with the dermis. These melanocytes form intricate protrusions extending into the keratinocyte layers of both the epidermis and hair follicle (indicated by keratin 10 in green). Within the dermis, auto-fluorescent elastin fibers (in red) are visible, accompanied by small nerve fibers (also marked by tubulin 3 in white) that project near the hair follicle and sebaceous gland. The hair and its shaft exhibit additional autofluorescence in white and red.

The November issue of the JID is out now! Take a look at this month's issue at https://t.co/ca0zprQP66 and the striking cover below.
#dermtwitter #dermatology #humanskin
The cover image reveals a highly detailed 3D reconstruction of a 20-micrometer-thick section of immune-stained human skin. It showcases the compact melanocyte lining (indicated by tubulin 3, in white) located at the junction of the epidermal and dermal layers. This lining forms complex protrusions that extend into the keratinocyte strata of the epidermis and hair follicles (marked by keratin 10, in green).
A sebaceous gland is discernible at the base of a hair follicle, and nerve fibers (also marked by tubulin 3, in white) can be found around the base of the hair follicle and within the dermis. Furthermore, auto-fluorescent elastin fibers of the dermis are shown in red.
The image stack was acquired on a confocal fluorescence microscope using a 40x silicon oil objective, stitched together, and rendered using Imaris software.

How do immune cells know where to go? It has been proposed that cells simply respond to externally established gradients of chemokines, but we think that’s not all…

[Science Immunology @SciImmunology]

Dendritic cells can “self-shape” the chemotactic gradients that help them transport antigens to lymph nodes, finds a new live imaging study from @Sixt_Lab @EdouardHannezo.
