Answer:
FSH
Explanation:
Luteinizing Hormone (LH) is a gonadotropin synthesized and secreted by the anterior pituitary gland in response to GnRH. Like FSH, LH is involved in reproductive processes in both males and females. When follicle maturation is complete, an LH surge triggers ovulation.
Answer:
Cytokines made by other innate cells, such as macrophages or dendritic cells
Explanation:
Innate Pattern Recognition Receptors (PRRs) on Dendritic cells and macrophages sense and respond to PAMPs and produce cytokines. Cytokines start the innate immune response.
The cytokines are produced in response to pathogen-associated molecular patterns (PAMPs) such as peptidoglycan monomers or CpG sequences on bacterial and viral genomes. Cytokines produced in response to pathogen receptors on cell surfaces, such as the inflammatory cytokines IL-1, IL-6, IL-8, and TNF-alpha, chemokines and type I interferons that act on leukocytes so as to promote and control early inflammatory responses.
