A system for delivering a payload to a cell that includes: a platform supporting an input container, an output container, and a receiver for receiving all or part of a disposable assembly, the disposable assembly including a preparation vessel and a constriction cartridge. The preparation vessel holds a cell suspension as it is prepared for passage through one or more cell-deforming constrictions, and the constriction cartridge houses a component that includes the one or more cell deforming constrictions. Passage through the cell-deforming constrictions causes perturbations in cell membranes to allow entry of a payload into the cells. The system includes one or more processors configured to receive input from a user and to automatically control pressure, temperature, agitation, and/or flow of the cell suspension as it passes through the input container, through the preparation vessel, through the constriction cartridge, and to the output container.

System for delivery of a payload into a cell

The present invention provides methods for inducing tolerance and/or suppressing an immune response to an antigen by passing a cell suspension containing an anucleate cell through a constriction, wherein the constriction deforms the cell thereby causing a perturbation of the cell such that an antigen and/or tolerogenic factor enters the cell. In some embodiments, the anucleate cell is delivered to an individual and the antigen is delivered to and processed in a tolerogenic environment to induce tolerance and/or suppress an immune response to the antigen.

Intracellular delivery of biomolecules to induce tolerance

The present application provides formulations of modified peripheral blood mononuclear cells (PBMCs), wherein the formulation comprises: PBMCs comprising at least one antigen (e.g., a human papillomavirus (HPV) antigen) and a cryopreservation medium. In some embodiments, the PBMCs are conditioned by incubating the PBMC in the presence of an adjuvant.

Formulations of PBMCs

The present application provides peripheral blood mononuclear cells comprising an antigen, methods of manufacturing such PBMCs, and methods of using such PBMCs, such as for modulating an immune response in an individual. In some embodiments, the PBMCs are conditioned by incubating the PBMC in the presence of an adjuvant.

Delivery of biomolecules to PBMCs to modify an immune response

The present disclosure pertains to methods for delivering a compound into a cell comprising a cell wall, including passing a cell suspension through a constriction, wherein said constriction deforms the cell comprising a cell wall, thereby causing a perturbation of the cell such that the compound enters the cell, wherein said cell suspension is contacted with the compound.

Intracellular delivery of biomolecules to cells comprising a cell wall

The present invention generally relates to systems and methods for receiving blood (or other bodily fluids) from a subject, e.g., from or beneath the skin of a subject. In some cases, the blood (or other bodily fluids) may be deposited on a membrane or other substrate. For example, blood may be absorbed in a substrate, and dried in some cases to produce a dried blood spot. In one aspect, the present invention is generally directed to devices and methods for receiving blood from a subject, e.g., from the skin, using devices including a substance transfer component (which may contain, for example, one or more microneedles), and directing the blood on a substrate, e.g., for absorbing blood. The substrate, in some embodiments, may comprise filter paper or cotton-based paper. After absorption of some blood onto the substrate, the substrate may be removed from the device and shipped or analyzed. In some cases, the device itself may be shipped or analyzed. For example, in some embodiments, a portion of the device may be sealed such that the substrate is contained within an airtight portion of the device, optionally containing desiccant. Other aspects are generally directed at other devices for receiving blood (or other bodily fluids), kits involving such devices, methods of making such devices, methods of using such devices, and the like.

Systems and methods for collection and/or manipulation of blood spots or other bodily fluids

The present invention generally relates to systems and methods for monitoring and/or providing feedback for drugs or other pharmaceuticals taken by a subject. In one aspect, the present invention is directed to devices and methods for determining a species within the skin of a subject; and producing feedback to a subject based on the determination of the species. The feedback may be, for example, visual, audible, tactile, a change in temperature, etc. In some cases, information regarding the determination of the species may be transmitted to another entity, e.g., a health care provider, a computer, a relative, etc., which may then provide feedback to the subject in some fashion. In some cases, the feedback may be directly indicative of the species. However, the feedback may also be indirect in some embodiments.

Systems and techniques for monitoring subjects

The present invention generally relates to devices and techniques associated with diagnostics, therapies, and other applications, including skin-associated applications, for example, devices for delivering and/or withdrawing fluid from subjects, e.g., through the skin. In some embodiments, the device includes a system for accessing an extractable medium from and/or through the skin of the subject at an access site, and a pressure regulator supported by a support structure, able to create a pressure differential across the skin at at least a portion of the access site. The device may also include, in some cases, a sensor supported by the support structure for determining at least one condition of the extractable medium from the subject, and optionally a signal generator supported by the support structure for generating a signal relating to the condition of the medium determined by the sensor.

Techniques and devices associated with blood sampling

The present invention generally relates to receiving bodily fluid through a device opening. In one aspect, the device includes a flow activator arranged to cause fluid to be released from a subject. A deployment actuator may actuate the flow activator in a deployment direction, which may in turn cause fluid release from a subject. The flow activator may also be moved in a retraction direction by a retraction actuator. In one aspect, the device may include a vacuum source that may help facilitate fluid flow into the opening of the device and/or may help facilitate fluid flow from the opening to a storage chamber. In one aspect, a device actuator may enable fluid communication between the opening and the vacuum source and the flow activator may be actuated after the enablement of fluid communication.

Delivering and/or receiving fluids

The present invention generally relates to receiving bodily fluid through a device opening. In one aspect, the device includes a flow activator arranged to cause fluid to be released from a subject. The flow activator may be actuated in a deployment direction by a deployment actuator, which may in turn cause fluid release from a subject. The flow activator may also be moved in a retraction direction by a retraction actuator. In one aspect, the device may include a vacuum source that may help facilitate fluid flow into the opening of the device and/or may help facilitate fluid flow from the opening to a storage chamber. In one aspect, an effector may enable fluid communication between the opening and the vacuum source and may do so in response to actuation of the flow activator.

Delivering and/or receiving material with respect to a subject surface

In some embodiments, the present invention generally relates to the separation of blood within a device to form plasma or serum. In some embodiments, the present invention generally relates to the removal of fluids, such as blood, contained within a device. In one aspect, the present invention is generally directed to systems and methods for receiving blood from a subject and processing the blood to form plasma or serum. For example, a device may be applied to the skin of a subject to receive blood from the subject and pass the blood through a separation membrane, which separates the blood into plasma and a portion concentrated in blood cells. As another example, blood or plasma may be allowed to clot within the device and serum (the unclotted portion of the blood) may be withdrawn from the device. The device may contain, in some cases, a vacuum source such as a pre-packaged vacuum to facilitate receiving of blood and/or passage of the blood through the separation membrane to produce plasma or serum. In certain embodiments, plasma, serum, or other fluids may be removed from the device by inserting a needle into a portion of the device that has reduced pressure, expelling gas into the device through the needle, then receiving plasma, serum, or other fluids through the needle.
