Cards

Term
VEGFR2
Definition
most potent, on ECs
Term
complement factor H
Definition
mutation (Tyr402His) is a risk for macular degeneration
Term
VEGF
Definition
secreted in response to hypoxia
Term
PHD & FIH
Definition
hydroxylate HIF-1a so it can be ubiquitinylated, inhibited by hypoxia
Term
HIF-1a
Definition
complexes with HIF-B and p300/CBP, induces VEGF and erythropoietin
Term
HIF-B & p300/CBP
Definition
complexes with HIF-1a, induces VEGF and erythropoietin
Term
MCP-1, VEGF
Definition
secreted by RPE, stimulate macrophages to produce TNF and TGF-B (scarring in macular degeneration)
Term
IGF & PDGF-AB
Definition
pro-angiogenic
Term
PEDF
Definition
anti-angiogenic
Term
cGMP-gated Na+ channel
Definition
closed by light, causes hyperpolarization as K+ escapes photoreceptor cell
Term
Rhodopsin
Definition
scotopsin and 11-cis-retinal
Term
BathoLumiMeta I-II ScoRho
Definition
transition states of rhodopsin after excitement by light
Term
Transducin
Definition
activated by trans pigment, stimulates cGMP-phosphodiesterase
Term
connexin32, MPZ, PMP22
Definition
mutated in Charcot-Marie Tooth Disease
Term
Hu
Definition
biomarker for small-cell lung carcinoma
Term
NF2 (merlin)
Definition
mutated in schwannomas
Term
NF1 (neurofibromin)
Definition
mutated in neurofibroma
Term
Serotonin
Definition
slow-wave sleep substance, contained in median raphe nuclei
Term
ACh
Definition
fired during REM by gigantocellular nucleus
Term
Norepi
Definition
decrease firing in REM in locus cerleus
Term
Hypocretin
Definition
fire when awake, decrease during sleep in lateral hypothalamus
Term
Histamine
Definition
high activity when awake, decrease during sleep in hypothalamus
Term
GABA
Definition
increases during sleep, inhibits wakeful areas in ventrolateral preoptic hypothalamus
Term
sleep polypeptides
Definition
isolated from CSF & blood, produces non-REM sleep when injected into 3rd ventricle, increased synthesis during wakefulness until it induces sleep
Term
Melatonin
Definition
secreted by pineal body, increased in darkness, decreased in light, some initiation of sleep, used to treat jet-lag and insomnia
Term
ATP, chormogranins, neuroactive peptides, dopamine B-hydroxylase
Definition
found in synaptic vessicles and chromaffin granules
Term
a1 Receptors
Definition
smooth muscle contraction, activate Gaq, PLC converts PIP2 to DAG&IP3, increases Ca2+
Term
a2 Receptors
Definition
presynaptic membrane, provide NE feedback, activate Gai, decrease cAMP/PKA/Ca2+/NE, increase vagal tone, decrease GI tone and motility
Term
B2 Receptors
Definition
smooth muscle relaxation, activate Gas, increase adenylate cyclase/cAMP/cGMP, decrease P-myosin, increase glycogen breakdown
Term
B3 receptors
Definition
in gallbladder and brain tissue, increase lipolysis and FFAs
Term
B1 receptors
Definition
on myocardium and impulse-conducting tissues, increase HR/impulse/contractility/myocardial relaxation
Term
Renin, Angiotensin II, vasopressin
Definition
Mean arterial pressure (MAP) increased by B1 effects
Term
MAO
Definition
most in liver/mitochondria of CA nerve terminals, converts CAs to MHPG
Term
COMT
Definition
in effector cells, converts CAs to methoxylated derivatives
