Antigen recognition is facilitated by invadosome-like protrusions formed by memory/effector T cells.
Sage PT, Varghese LM, Martinelli R, Sciuto TE, Kamei M, Dvorak AM, Springer TA, Sharpe AH, Carman CV. Sage PT, et al. Among authors: dvorak am. J Immunol. 2012 Apr 15;188(8):3686-99. doi: 10.4049/jimmunol.1102594. Epub 2012 Mar 21. J Immunol. 2012. PMID: 22442443 Free PMC article.
The resulting calcium flux stabilized dense arrays of ILPs (each enriched in TCR, protein kinase C-teta, ZAP70, phosphotyrosine, and HS1), forming what we term a podo-synapse. Similar findings were made using CD8 CTLs on endothelium. ...

Vascular hyperpermeability, angiogenesis, and stroma generation.
Nagy JA, Dvorak AM, Dvorak HF. Nagy JA, et al. Among authors: dvorak am. Cold Spring Harb Perspect Med. 2012 Feb;2(2):a006544. doi: 10.1101/cshperspect.a006544. Cold Spring Harb Perspect Med. 2012. PMID: 22355795 Free PMC article. Review.
This article places tumor vascular hyperpermeability in a broader context, relating it to (1) the low-level "basal" permeability of the normal vasculature; (2) the "acute," short-term hyperpermeability induced by vascular permeability factor/vascular endothelial growth fac …

TM4SF1: a tetraspanin-like protein necessary for nanopodia formation and endothelial cell migration.
Zukauskas A, Merley A, Li D, Ang LH, Sciuto TE, Salman S, Dvorak AM, Dvorak HF, Jaminet SC. Zukauskas A, et al. Among authors: dvorak am. Angiogenesis. 2011 Sep;14(3):345-54. doi: 10.1007/s10456-011-9218-0. Epub 2011 May 29. Angiogenesis. 2011. PMID: 21626280 Free PMC article.
TM4SF1 is necessary for the formation of unusually long (up to a 50 mum), thin (~100-300 nm wide), F-actin-poor EC cell projections that we term 'nanopodia'. Immunostaining of nanopodia at both the light and electron microsopic levels localized TM4SF1 in a regularly spaced …

Ribonuclease-gold ultrastructural localization of heparin in isolated human lung mast cells stimulated to undergo anaphylactic degranulation and recovery in vitro.
Dvorak AM, Morgan ES. Dvorak AM, et al. Clin Exp Allergy. 1999 Aug;29(8):1118-28. doi: 10.1046/j.1365-2222.1999.00547.x. Clin Exp Allergy. 1999. PMID: 10457117
A previously developed post-embedding, enzyme-affinity-gold electron microscopic technique to image ribonucleic acid (RNA) with ribonuclease-gold (R-G), which also binds to the enzyme inhibitor, heparin, was employed to determine the sub-cellular locations of heparin in non-secre …

Hyperfibrinolysis in a case of myelodysplastic syndrome with leukemic spread of mast cells.
Wimazal F, Sperr WR, Horny HP, Carroll V, Binder BR, Fonatsch C, Walchshofer S, Födinger M, Schwarzinger I, Samorapoompichit P, Chott A, Dvorak AM, Lechner K, Valent P. Wimazal F, et al. Among authors: dvorak am. Am J Hematol. 1999 May;61(1):66-77. doi: 10.1002/(sici)1096-8652(199905)61:1<66::aid-ajh12>3.0.co;2-3. Am J Hematol. 1999. PMID: 10331514 Free article.
We report a 75-year-old male patient with myelodysplastic syndrome (MDS) of recent onset (3 months' history) associated with a massive leukemic spread of immature tryptase+ MC (tentative term: myelomastocytic leukemia). The patient presented with pancytopenia, bleeding, hy …

Ribonuclease-gold labels heparin in human mast cell granules. New use for an ultrastructural enzyme affinity technique.
Dvorak AM, Morgan ES. Dvorak AM, et al. J Histochem Cytochem. 1998 Jun;46(6):695-706. doi: 10.1177/002215549804600601. J Histochem Cytochem. 1998. PMID: 9603780
Extensive studies revealed that HMCs isolated from lung or skin and sustained in short-term cultures, derived de novo in growth factor-supplemented cord blood cell cultures, or present in vivo in multiple sites all shared this property. ...

Recovery of human basophils after FMLP-stimulated secretion.
Dvorak AM, Warner JA, Fox P, Lichtenstein LM, Macglashan DW. Dvorak AM, et al. Clin Exp Allergy. 1996 Mar;26(3):281-94. Clin Exp Allergy. 1996. PMID: 8729665
In one species of guinea-pigs, basophilic leucocytes have been shown to recover from stimulated secretion in short-term cultures. Similar studies have not been done using human basophils. OBJECTIVE: The purpose of this study was to examine human basophils in short-term …
