Insights

Human chorionic gonadotropin (hCG) therapy in cryptorchid boys temporarily reduced T suppressor-cytotoxic cells (CD8+) and lymphocyte response. Immune parameters returned to normal after hCG treatment cessation.

Area of Science:

  • Pediatric Endocrinology
  • Immunology
  • Reproductive Medicine

Background:

  • Cryptorchidism, undescended testes, affects male reproductive health.
  • Immune system function in prepubertal boys with cryptorchidism requires further investigation.
  • Hormonal therapies, like human chorionic gonadotropin (hCG), are used to treat cryptorchidism.

Purpose of the Study:

  • To evaluate humoral and cellular immunologic parameters in prepubertal cryptorchid boys.
  • To assess the impact of hCG therapy on immune cell populations and function.
  • To determine if immune parameters normalize after hCG treatment withdrawal.

Main Methods:

  • Longitudinal study of 13 prepubertal boys with cryptorchidism.
  • Immunologic parameters assessed before, during, and 3 months after hCG therapy.
  • Flow cytometry used to analyze T cell subsets (CD8+).
  • Lymphocyte proliferation assays (ConA) conducted.

Main Results:

  • Pre-treatment: Elevated percentage of T suppressor-cytotoxic cells (CD8+).
  • During hCG therapy: Significant decrease in CD8+ cell percentage and lymphocyte response to ConA.
  • Post-treatment: Immune parameters returned to baseline levels after hCG withdrawal.

Conclusions:

  • hCG therapy transiently alters specific immune parameters in prepubertal cryptorchid boys.
  • The immune system appears to recover normal function after cessation of hCG treatment.
  • Long-term effects of hCG on the immune system warrant further investigation.

Transcytosis of IgG01:15

Transcytosis of IgG

Transcytosis is the process in which molecules are internalized by endocytosis, transported across the cell, and released through exocytosis from the opposite end of the cell. Molecules such as insulin, immunoglobulins, and certain nutrients are transferred through the recycling endosomes by recycling and transcytosis.
IgG molecules from a mother undergo transcytosis starting around 13 weeks of gestation. The amount of IgG transferred and entering the fetal blood circulation increases with...
Cytotoxic T Cells-mediated Immune Response01:27

Cytotoxic T Cells-mediated Immune Response

Cytotoxic T cells are a vital component of the immune system. They have the remarkable ability to identify and target antigens on infected or abnormal cells. These antigens often originate from intracellular pathogens such as viruses or abnormal proteins cancer cells produce.
Immunological surveillance is the ability of immune cells to monitor and eliminate infected cells with intracellular pathogens, neoplastically transformed cells, and cells with non-self antigens. Cytotoxic T cells and NK...
Development of Immunocompetence01:22

Development of Immunocompetence

The initiation of cell-mediated immunity can be observed as early as the third month of fetal growth, with active antibody-mediated immunity following approximately one month later.
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
Subsequent T...
Immunodeficiency Diseases01:25

Immunodeficiency Diseases

Immunodeficiency disorders are conditions in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. The immune system comprises a complex network of cells, tissues, and organs that work together to protect the body from potentially harmful invaders. When this system is deficient or not functioning properly, it leaves the body susceptible to infections, diseases, or other complications.
There are three main causes of immunodeficiency disorders...
Ovarian Cycle01:27

Ovarian Cycle

The menstrual cycle includes a critical component known as the ovarian cycle, which undergoes two main phases each month—the follicular phase and the luteal phase. The follicular phase is variable and averaging around 14 days. Ovulation, triggered by a surge in luteinizing hormone (LH), marks the transition between the two phases. The second phase, the luteal phase, is relatively consistent, lasting approximately 14 days, and is marked by the activity of the corpus luteum. While a cycle length...
Inhibitors of Viral Protein Synthesis01:30

Inhibitors of Viral Protein Synthesis

Protein synthesis is indispensable for viral replication, as viruses lack the cellular machinery required for this process and must hijack the host's translational apparatus. In response, host cells deploy a critical innate immune defense involving interferons, specialized cytokines that play a central role in inhibiting viral propagation.Upon viral detection, infected cells release interferons that bind to receptors on adjacent uninfected cells, activating the JAK-STAT signaling pathway and...
