A method of detecting integrated stress response activity in living cells comprising inducing UL148-marker expression, scanning the cells to determine if the UL148 is punctate or diffuse, and ranking the level of ISR activity based on how punctate the UL148 is in the cell. The marker may be a fluorescent marker. The fluorescent marker may be Green fluorescent protein. The cell may be an epithelial cell. The cells may be ARPE-19 epithelial cells carrying a doxycycline inducible gene expression cassette encoding UL148-GFP and treating the cells for 18 hours with 100 ng/mL doxycycline hyclate to induce UL148-GFP expression. The cells may have an inducible gene expression cassette encoding UL148-marker expression. The UL148-marker expression may be induced by the cell being treated with an antibiotic. The method may include adding marker to the cells. The cells may be mutated to express UL148-marker upon inducement. A kit to conduct the method.

Disclosed are vaccine-derived neutralizing antibodies (NAbs) for CMV infections and small peptides which define precise recognition elements of the antigens by the NAbs. In certain embodiments, vaccine-derived NAbs may be produced by immunizing a subject with a gH/gL/UL128/UL130/UL131A pentameric glycoprotein complex (gH/gL-PC). In certain embodiments, vaccine-derived NAbs may have properties similar or identical to those of NAbs induced in a subject naturally infected with CMV. Native and non-native small peptides from UL128 and gH have been defined by mapping epitopes and deriving artificial sequences which are minimal recognition elements of vaccine-derived NAbs disclosed herein. These small peptides can be used to elicit vaccine-derived NAbs that prevent CMV entry into susceptible cell types and protect humans from infection and disease. Multivalent vaccines comprising these small peptides and/or epitopes are also disclosed. Kits and methods of using the vaccine-derived NAbs and small peptides disclosed herein including methods of treating or preventing CMV infection in a subject are also provided.

Provided herein are methods of treating or preventing human cytomegalovirus (HCMV) infection comprising modulating interactions between the HCMV gH/gL/UL128-131A pentamer and plasma membrane-expressed host cell proteins, as well as methods of identifying modulators of such interactions.
