Subarachnoid lymphatic-like membrane
The Subarachnoid Lymphatic-like Membrane (SLYM) is an anatomical structure in the human brain that represents a fourth layer of the meninges.
The SLYM is located in the subarachnoid space, the space between the middle reticular meninges and the innermost tender meninges that lie close to the brain.[1] It divides the subarachnoid space into an outer, superficial compartment and an inner, deeper area surrounding the brain.[1]
Structure
The SLYM is very thin, but consists of several cell layers and contains its own immune cells.[1] It is similar in structure to the lymphatic vessels in the body and could therefore play an important role in immune protection and fluid balance in the brain.[1] It consists of only a few layers of cells and is similar in nature to the mesothelium. The SLYM prevents larger molecules such as peptides and proteins from passing into the interior of the brain and could thus assume a barrier function.[1]
Discovery and importance
According to the publication in 2023, the SLYM is a newly discovered anatomical structure in the human brain.[2] The discovery of the SLYM represents an important addition to existing anatomical knowledge and may contribute to new insights into brain function and potential therapeutic approaches.[1] However, further studies are needed to better understand the exact function and potential clinical relevance of the SLYM.
