Functions of the Lymphatic and Immune System01:28

Functions of the Lymphatic and Immune System

6.9K
The lymphatic system plays a crucial role in bolstering our immune system. It consists of a network of lymphoid organs, lymph, and lymphatic vessels that provide structural and functional support in safeguarding the body against pathogens such as viruses and bacteria.
The primary lymphoid organs, including the bone marrow and the thymus, serve as the maturation sites for lymphocytes. Secondary lymphoid organs, like the mucosa-associated lymphoid tissue, activate these lymphocytes and serve as...

Testosterone: Functions and Regulation

2.3K
The intricate hormonal interplay essential for male reproductive health begins with the release of gonadotropin-releasing hormone (GnRH) by the hypothalamus. This hormone prompts the pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). LH targets the Leydig cells in the testes, stimulating them to produce and release testosterone. In concert with testosterone, FSH acts on the Sertoli cells within the seminiferous tubules to facilitate the release of...

Anatomy of the Brain: Ventricles

9.1K
There are hollow fluid-filled cavities known as ventricles deep inside the human brain. There are two lateral ventricles, one in each cerebral hemisphere, and each has three different projections — the anterior, inferior, and posterior horns visible from the lateral side. A thin membrane called the septum pellucidum separates the two lateral ventricles. The slender third ventricle in the diencephalon is connected to each lateral ventricle via a channel called the interventricular foramen.

Lateralization01:28

Lateralization

1.1K
Brain lateralization refers to the division of mental processes and functions between the two hemispheres of the brain, a phenomenon that optimizes neural efficiency and underpins complex abilities in humans. This specialization allows each hemisphere to perform tasks where it has a comparative advantage, facilitating more refined cognitive capabilities across different domains.

GTPases and their Regulation02:14

GTPases and their Regulation

9.9K
Guanine nucleotide-binding proteins (G-proteins), also known as GTPases, are a superfamily of proteins that regulate many cellular processes, such as cell signaling, vesicular transport, and the regulation of cell shape and motility. Mutation or dysfunction of these proteins can lead to disease. There are around 40,000 known G-proteins that can broadly be classified into two groups ‒  small G-proteins consisting of a single domain and large multi-domain G-proteins.
Large G-proteins,...

Summary

Galectin-3 (Gal-3) protein aids innate immunity by recognizing pathogens. This review explores Gal-3

Area of Science:

  • Neuroimmunology
  • Innate Immunity
  • Glycobiology

Background:

  • Galectin-3 (Gal-3) is a conserved protein involved in innate immunity.
  • Its role in mammalian anti-infective defense is less understood than its role in inflammation.
  • The cerebrospinal fluid brain interface (CSFBI) is a potential route for brain infections.

Purpose of the Study:

  • To review the potential roles of Galectin-3 in pathogen recognition at the CSFBI.
  • To highlight Gal-3's function in combating bacterial and viral infections.
  • To suggest future research directions for Gal-3's anti-infective properties.

Main Methods:

  • Literature review and synthesis of existing research on Galectin-3.
  • Analysis of Gal-3 expression in ependymal cells (ECs) at the CSFBI.
